SOURCE: O2 sensor problem

I have a 97 gmc sierra .This truck is the same as the chevy ok.Its a 350 5.7 liter 4x4 Z71.I took it to auto zone which was my first mistake.They put it the scanner and said bad O2 sensor.Ok so which one is it i said.They dont know.Well there four (4) O2 sensors in this truck i hope you know that.I had to replace all four of them before i had to take it to a real shop.It seems the fuel pump i replaced a week earlier with an auto zone fuel pump was bad.Ive changed my feul pump 4 times now and have 235000 miles on still running.You need to get your fuel pressure checked.It should be 65 psi to start it and 55 psi to run it.If the pressures are good it could be a different O2 sensor or maybe the mass air flow senor.My last option would be the fuel pressure regulator because it seems to be a waste of time and money.I would get that fuel pressue checked first.Good luck.

SOURCE: 2002 chevrolet avalanche how do you know when

If you have a bad booster you would have a really hard pedal and it would take two feet to stop. Sounds more like a fluid leak or a bad master cylinder. Are you adding fluid or do you have a red brake light on?

SOURCE: I tried to remove spare tire but it will only drop about 2 inches which is not enough to remove it. Any suggestions?

Check your owners manual .There is a saftey catch that will need to be realased by using your bottle jack and tire stops that come with your truck. If you dont have a owners manual. What you can try is taking a floor jack and a socket place it under the spairtire right in the center where the cable holds the tire in place. start jacking it up until the socket hits the square part in the center once the socket is aligned with the square part continue to jack up it should release it . Its a stupid system but it will work if the cable wont allow the tire to drop .I drive a tow truck and this has happened to me several times with people who have this type of system on a GM.

Air supension stays too high


There could be a couple of problems, first and easiest is the rear height sensor became disconnected from its mount. This is common because the sponsor clips on by a kinda weak spring and can be easily disconnected.also where the sensor mounts is a small round metal ball that screws onto frame and rear suspension, the balls after time wear to the point that the sensor spring cannot hold on.there's also an adjustment on the lower mount, if you move it up the vehicle will lower....then you could have a concern with the air compressor vent not allowing it to vent down to ride height. Or the vent solenoid on top of each bag stuck also not allowing it to vent..to ck it yourself, go for a short ride around the block and when you come back park on a level surface, shut off car, exit and close door....listen for an auditable click in the rear, and front left corner of car and watch the distance between rite and wheel lip, see if it drops. If it does I would be leaning towards the simple adjustment...also check thr front ride height on level surface, if you have a suspension problem on 1side of the car and it sits lower,it will throw off rear ride height. ...

I have 2002 f150 and took the torsion bars out and not know to mark the spline the torsion bar has a yellow dot on it but control arm don't how do i get it it back to factory ride


jack up the vehicle around 3 inches so that both wheels are lower than the front cross member. Net install the torsion bars . On the splined lock you will find a locked screw that adds tension to the bar . Set this screw about 1/2 way. Place the splined lock on the bar so that the screw is touching the solid mount part. Lower the vehicle and see where it is sitting. If it is too low then re jack it up higher and re- position the block on the spline one more spline around . lower the vehicle again and check the ride height. Repeat the process until you get to a point where the adjusting the screw will level out the vehicle IF one spile is too high or just a bit too low then the screw should take up the difference. Lock the screw nut when finished

I want to know how to fix the alignment on my 1995 honda accord ex.


Before making wheel alignment adjustment, perform the following checks:
  1. Tires should be equal in size and runout must not be excessive. Tires and wheels should be in balance, and inflated to manufacturer's specifications.

  2. Wheel bearings must be properly adjusted. Steering linkage and suspension must not have excessive looseness. Check for wear in tie rod ends and ball joints.
  3. Steering gear box must not have excessive play. Check and adjust to manufacturer's specifications.
  4. Vehicle must be at curb height with full fuel load and spare tire in vehicle. No extra load should be on vehicle.
  5. Vehicle must be level with floor and with suspension settled. Jounce front and rear of vehicle several times and allow it to settle to normal curb height.
  6. If steering wheel is not centered with front wheels in straight-ahead position, correct by shortening one tie rod adjusting sleeve and lengthening opposite sleeve equal amounts.
  7. Ensure wheel lug nuts are tightened to torque specifications
Ride Height Adjustment

Before adjusting alignment, check riding height. Riding height must be checked with vehicle on level floor and tires properly inflated. Passenger and luggage compartments must be unloaded. Bounce vehicle several times, and allow suspension to settle. Visually inspect vehicle from front to rear and from side to side for signs of abnormal height.
Measure riding height. See figure. Riding height between left and right sides of vehicle should vary less than 1′ (25.4 mm). If riding height is not within specification, check suspension components and repair or replace them as necessary.
Wheel Alignment Procedures

Honda recommends using commercially available computerized 4-wheel alignment equipment. Follow equipment manufacturer instructions to obtain vehicle alignment settings. Use following procedures for necessary adjustments.
Civic Camber Adjustment
Compare camber settings with vehicle manufacturer recommendations. If camber is incorrect, check for bent or damaged front suspension components. Replace faulty components. Recheck camber.
Civic Caster Adjustment
DO NOT use more than 2 shims. If more than 2 shims are required to adjust caster angle, check for bent or damaged suspension components.
Compare caster settings with vehicle manufacturer recommendations. If caster is incorrect, check for bent or damaged front suspension components. Replace faulty components. Recheck caster.
Civic Toe-In Adjustment

  1. Secure steering wheel in straight-ahead position. Measure front wheel toe-in. If adjustment is needed, loosen tie rod lock nuts. Turn both tie rods equally in the same direction until front wheels are in straight-ahead position and toe-in reading is correct. Tighten tie rod lock nuts. Reposition tie rod boots if twisted.
  2. Ensure parking brake is released. Check rear wheel toe-in. If adjustment is needed, hold adjusting bolt on rear compensator arm and loosen lock nut. See figure. Adjust rear toe-in by sliding rear control arm until rear toe-in is correct. Install NEW lock nut, and tighten it while holding adjusting bolt.

I need to know in what order does the torsion bar linkage go. I took my blazer to the garage to get it inspected and they told me that they were put on wrong.


Aint much to a torsion bar, it has 2 identicle ends. Both ends are hexigon shaped. And only one adjustable screw, one for each side. Tighten it, and it will raise the front of your vehicle, loosen it, and it lowers the front of your vehicle. All torsion bars are not equal, so a set amount of turns to adjust is not a fix all solution. Mine is 10-1/2 turns from first thread contact, but, you need about a 1/2 inch of clearance from lower arm to lower bump stop. Or to find the Z hieght of your blazer. Measure from the center of your lower arm bolt/pin to the ground (vehicle must be level). then measure from the bottom of the stearing knuckle to the ground. Subtract the two measurements, you want 4.9 inches(4" 7/8"). The higher you turn the torsion bar to raise your front end. the more problems you will have, especially rough riding.

P.S. You can do this adjustment without jacing up the Blazer. But if you have to tighten the adjustment screw, it can be tough. I suggest jacking up one side, Use a jack stand for safety! make an adjustment, then lowewr the vehicle. rock it back and forth to let the suspension settle and measure again. and repeat till all is well.

1996 seville rear air ride too high


The ride level system uses an air compressor and either an air type of shocks or a type of air billow to raise and lower the vehicle, there is an adjustment to set the ride height and it is located under the vehicle and there is a control lever or rod that should be connected between the rear axle and a switch that is mounted on the body of the vehicle, and there will be an adjustment slot in the control lever between the switch and the body, and that is how you would adjust the ride level height, but be sure that the vehicle can not drop any further down if someone is under the vehicle trying to adjust the ride height.

However, you might find that the control lever to the ride level has fallen off from the switch on the body or it has come loose from the rear axle, and it is just hanging there not operating the switch on the body that controls the the ride level compressor.

Lincoln navigator air suspension is all the way down


that should not happen. Did you turn the switch off in the back for the suspension? Did you do something else at the same time, like check the spare tire for air pressure?

I have info on 2003 navigator 4 wheel air suspension. Maybe similar

SECTION 204-05: Vehicle Dynamic Suspension — 4-Wheel 2003 Expedition/Navigator Workshop Manual
DESCRIPTION AND OPERATION Vehicle Dynamic Suspension The four wheel air suspension system is comprised of the following components:
  • service switch
  • control module
  • two front height sensors
  • one rear height sensor
  • compressor and drier assembly (includes vent solenoid)
  • air lines
  • front and rear air spring and shock absorber assemblies
  • four air spring solenoids
WARNING: The service switch for the air suspension system must be shut off prior to hoisting, jacking or towing an air suspension vehicle. This can be accomplished by turning off the air suspension switch located in the jack storage area in the rear of the passenger compartment. Failure to do so may result in unexpected inflation or deflation of the air springs which may result in shifting of the vehicle during these operations.

WARNING: Do not remove an air spring under any circumstances when there is pressure in the air spring. Do not remove any components supporting an air spring without either exhausting the air or providing support for the air spring to prevent vehicle damage or personal injury.

------------------------------
Principles of Operation
The 4-wheel air suspension (4WAS) module commands changes in vehicle height that are necessary for both the load leveling and the vertical height adjustment features.
The 4WAS load leveling feature automatically makes adjustments in vehicle height so that the vehicle is always at trim height, and that constant front-to-rear vehicle attitudes are maintained over the load range of the vehicle. Adjustments in height that are necessary to correct height differences between the vehicle left and right sides for the 4WAS system are restricted to what can be reliably achieved with three height sensors.
The height adjustment feature has three vehicle heights within a two-inch span:
Kneel height — improves the ease of entering and exiting by lowering the vehicle one inch below the trim height in the front and rear when the vehicle ignition is in the OFF or LOCK positions and the vehicle is stationary.
Trim height — normal vehicle ride position; vehicle moves to trim position when the ignition is ON, when the transmission is initially shifted to DRIVE or REVERSE mode, when all doors are closed or when speed of more than 24 km/h (15 mph) is detected.
Off-road height — improves ground clearance by raising the vehicle one inch above trim height in the front and rear when the vehicle is at 4x4 low modes and the vehicle speed is less than 40 km/h (25 mph).
The 4WAS module uses the universal bus protocol, (UBP), module communications network for sending and receiving various signals with the exception of speed, information from the three height sensors, and the air suspension service switch. For additional information about UBP, refer to Section 418-00 .
The 4WAS system holds vehicle height when any door or rear hatch is opened. The system stores front and rear vehicle height the moment any door is detected open. The system then maintains this height regardless of the addition or removal of a load. The system returns to its commanded height when all doors are closed or vehicle speed exceeds 24 km/h (15 mph).

-------------------------------
Air Suspension Service Switch
The air suspension service switch signal is needed to wake up the 4WAS module. Without the module receiving this signal, the 4WAS system is inoperative at speeds below 24 km/h (15 mph) and will not react when the vehicle is raised or lowered. At speeds above 24 km/h (15 mph), the system will be active as if the air suspension service switch is in the ON position.
Vehicles without message center When the air suspension service switch is in the OFF position and the ignition switch is in the RUN position, a "CHECK SUSP" will appear in the RH corner of the instrument cluster.
Vehicles with message center When the air suspension service switch is in the OFF position and the ignition switch is in the RUN position, the message center will display "SUSPENSION SWITCHED OFF"
-------------------------------------------
Inspection and Verification
  1. Verify the customer concern.
  1. NOTE: If the door ajar indicator is illuminated when all doors, liftgate, and liftgate glass are closed, the air suspension will not work correctly. Repair door ajar indicator; refer to Section 413-01 .
    Visually inspect for obvious signs of mechanical and electrical damage.


Visual Inspection Chart Mechanical Electrical
  • Restricted suspension movement
  • Excessive vehicle load
  • Cut, severed, crimped air line(s)
  • Unmounted height sensor(s)
  • Damaged front air spring(s)
  • Damaged rear air spring(s)
  • Battery junction box (BJB) fuses 20 (30A), fuse 27 (5A), and fuse 111 (50A)
  • Loose, corroded, or disconnected connectors
  • Air suspension service switch is in the OFF position
