Question about 1999 Ford Ranger SuperCab

2 Answers

While I am driving if I maintain a constant speed between 50 and 55 mph the truck will occasianally feel like it studders for a second then continues with a smooth ride for a few minutes then it happens again. At higher or lower speeds I do not feel this hesitation. no cel or trouble other than what I stated

No MIL Lamp does not mean no codes stored

Need to go for a ride with a scanner on it & look
at cylinder misfire counts,egr,O2 sensors,fuel trim &
the 8 emission monitors,then possibly do some component
testing

Most likely ignition misfires,mechanical issue with valve train
many possiblities

Might want to check to see if you have a bent rim or a bad tire.

SOURCE: Maybe a transmission problem?

If you're only in "D", you should switch to "OD" when driving at higher speeds. "D" only allows you to move up to third gear whereas "OD" will move you into fourth. You're over-working your transmission by driving in "D".

In addition to the above, also try cleaning the Mass Air Sensor. it is located just past your air cleaner going back towards the engine. Just unscrew the to star bolts and you will see a small fillament when you remove the sensor. If it is not shinney and appears dirty, give it a qiuck blast of carb cleaner and then let it dry for a minute. Put the sensor and bolts back in and see if that helps. I have used this on two Ford Ranges and an Explorer. Seems to help a rough running older engine.

The trans is controlled by the computer. There should be something that a scanner will tell you if you have it scanned. It is good that the rpm's are staying steady. You may have a drivablity problem that is showing up while it is in lock up mode. This will amplify a miss in the engine. The 5.4 is a motor that few tune up because of how hard it is to replace the back four plugs. Try a good tune up and fuel injection cleaning if there are no codes in the computer to indicate another problem.

2002 chevy s10 temperature gauge jumping around, feels like automatic transmission slipping at speeds above 60 mph


Do you have an OBDII scanner to check the real temperature? Want to make sure it's not overheating. If it's normal, could be your temperature sensor starting to go out, or ignition switch. Any check engine lights? If so, get the code for me, can go from there. At a constant speed, you sure it wasn't a misfire instead? Check your trans fluid, make sure it's full. I was just in Tahoe, pretty sad not much snow at all.

Tip

Save Money on Gas/Petrol


  1. Avoid idling. While idling, your car gets exactly 0 miles per gallon while starting the car uses the same amount as idling for 6 seconds. Park your car and go into the restaurant rather than idling in the drive-through. Idling with the air conditioning on also uses extra fuel. Also, avoid going so fast that you have to brake for someone. Whenever you brake, you waste the gas it took to get going that fast.
  2. Drive at a consistent speed. Avoid quick acceleration and hard braking. Cruise control will keep you at a constant speed, even when going up and down hills.
  3. Avoid stops. If approaching a red light, see if you can slow down enough to avoid having to actually stop (because you reach the light after it is green). Speeding up from 5 or 10 miles per hour will be easier on the gas than starting from full stop.
  4. Anticipate the stop signs and lights. Look far ahead; get to know your usual routes. You can let up on the gas earlier. Coasting to a stop will save the gasoline you would otherwise use maintaining your speed longer. If it just gets you to the end of a line of cars at a red light or a stop sign a few seconds later, it won't add any time to your trip. Ditto for coasting to lose speed before a highway off-ramp: if it means you catch up with that truck halfway around the curve instead of at the beginning, you haven't lost any time. In many cities, if you know the streets well, you can time the lights and maintain the appropriate speed to hit all green lights. Usually this is about 35 to 40 MPH.
  5. Slow down. Air resistance goes up as the square of velocity. The power consumed to overcome that air resistance goes up as the cube of the velocity. Rolling resistance is the dominant force below about 40 mph. Above that, every mph costs you mileage. Go as slow as traffic and your schedule will allow. Drive under 60-65 since air grows exponentially denser, in the aerodynamic sense, the faster we drive. To be precise, the most efficient speed is your car's minimum speed in it's highest gear, since this provides the best "speed per RPM" ratio. This is usually about 45 to 55 miles per hour.
  6. Use A/C only on the highway. At lower speeds, open the windows. This increased the drag and reduces fuel efficiency, but not as much as the AC at low speeds (35-40 mph). The air con - when used a lot - is known to use up about 8% of the fuel you put into your car.

2007 HONDA ACCORD SECOND GEAR SHUDDER


Well, you did a really good job of describing the symptoms, but you didn't do so well describing the car. Are we talking about an automatic or standard transmission? are we talking about a four or six cylinder engine? You are asking about a drivetrain problem without giving any information about what drivetrain the vehicle is equipped with.

With all that said, IF we are talking about an automatic transmission being pushed by a V-6 engine, then there is a Technical Service Bulletin (TSB) that matches the symptoms you are describing. In this case, the problem is most likely being caused by a deformed or damaged exhaust pipe "A" mounting bracket.

Inspect the rubber bracket for cracks or torn rubber. If the bracket is damaged replace the bracket. Bend the stud on the exhaust pipe if necessary to get the stud to go through the bracket as straight as possible so the stud does not "ground" against the sides of the bracket. (see diagram)

I have a 2001 nissan pathfinder 4w. The OBD system-readiness status: Says catalytic converters, NOT READY; oxygen sensors, NOT READY; evaporative system, NOT READY. So did not pass inspection, I was told...


You have to re-set the obd via using Nissan's approved drive-cycle which is;

1. Start the engine when the engine coolant

temperature gauge needle points to C. Allow

the engine to idle until the gauge needle

points between the C and H (normal operating

temperature).

2. Accelerate the vehicle to 55 MPH (88

km/h), then quickly release the accelerator

pedal completely and keep it released for at

least 6 seconds.

3. Quickly depress the accelerator pedal for a

moment, then drive the vehicle at a speed

of 53 to 60 MPH (86 to 96 km/h) for at least

5 minutes.

4. Stop the vehicle.

5. Accelerate the vehicle to 35 MPH (55 km/h)

and maintain the speed for 20 seconds.

6. Repeat steps 4 through 5 at least 3 times.

7. Accelerate the vehicle to 55 MPH (88 km/h)

and maintain the speed for at least 3 minutes.

8. Stop the vehicle and turn the engine off.

9. Repeat steps 1 through 8 at least one more

time.

If step 1 through 7 is interrupted, repeat the

preceding step. Any safe driving mode is acceptable

between steps. Do not stop the engine

until step 7 is completed. If you cannot or

do not want to perform the driving pattern, a
NISSAN dealer can conduct it for you.
