SOURCE: my engine seems like it

there area few different problems that can cause this to happen. If the check engine light is on, you can take it to a local auto parts store, and they will have a basic OBD II scanner and usually can point ya in the right direction as to where the problem is. Personally I would start with checking the throttle position sensor, these are notorious for going out on the 3.8.

SOURCE: monte carlo slow acceleration Problems

Check the fuel filter. Most of the time you'll find that a clogged fuel filter will cause slow acceleration. Another problem may be the catalytic convertor, which may have crapped out. Please rate this advice.

SOURCE: need to remove rack and pinion on 98 monte carlo

To start: Make sure the steering shaft and or wheel is not turned during this repair =|= You can damage the air bag system coil. Put the key in and lock the wheel or use a seat-belt and tie off the wheel so it will not turn.  Take the battery loose. check your radio for any codes to reset it after finished or turn off the lockout before you disconnect the battery. If you have a 3.4 DOHC engine remove the air cleaner and duct work.  You will have to jack up the front of the car and make it secure with good supports and locking the rear wheels, You will be under the car so - be safe, be sure, be safe. You have to remove the front tire/wheels and your jack stands have to be behind the front sub-frame, you can not use the sub-frame for support during this job. Set the wheel straight ahead. Pull back the boot at the bottom of the steering column shaft, mark the coupler and steering input shaft.  If you have the 3.4L DOHC remove the right side engine splash shield, and the exhaust pipe / catalytic converter assembly .  Separate the tie-rods ends from the steering arms. support the rear of the sub-frame with a jack giving room to access the rear most part of the sub-frame. Remove the rear sub-frame bolts, loosen the front bolts Do Not Remove them!!! lower the rear approx 5 inches DO NOT LOWER TO MUCH YOU CAN DAMAGE SOME ENGINE COMPONENTS.  Remove the heat shield form the steering gear. Take any pipe or hoses loose form support clips on the body. You will need a drain pan to catch any fluid that drains out. Using a flare nut wrench take loose the pressure and return lines from the gear. Plug the lines to stop fluid from draining out of the lines. Remove the gear retaining nuts and bolts. Pull the gear out of the supports move it forward and detach the steering coupler from the steering shaft. Support the gear and it comes out the left side wheel opening.  To reinstall pass the new gear through the left wheel opening and place it in position in the mounts reinstall the shaft coupler and the bolts/nuts in the supports. reattach the lines, the heat shield, and if you can find them you should use new sub-frame bolts, run the rear in first and then the front, one at the time and torque the bolts to 133 ft-lbs. Reconnect the tie rods to the steering arms. Reinstall the exhaust system now. Check the wheel center using the marks made on the shaft, be sure the coupler is seated before you tighten the pinch bolt. Reinstall the front wheels, lower the car off the stands. Reconnect the battery. Fill the power steering pump to the recommended level start up the car and ck for leaks, have the alignment checked per a tire / alignment shop.

Backfire at 60 to 70 mph


Check for bad fuel, but it sounds like it might be spark plugs or spark plug wires breaking down and cross firing or missing. If it is electrical you should have a rougher idle also.

Does it misfire under load like when you press on the gas peddle after slowing down then accelerate or at idle. When you say spark plug did you mean all the spark plugs?

Why does my 1998 sebring idle fine but sputter badly under load.


Does it use spark plug wires or individual ignition coils for the each plug?. My 98 intrepid uses coils and occasionally I have to change them out cause it would start to miss when normal temperature was achieved. If it uses wires, try replacing them, along with the spark plugs.

I have a 95 monte carlo LS miss fire while idle


Hi and welcome to FixYa!

As a first course of action I strongly suggest that you replace the spark plugs and plug wires. If the plugs and plug wires are worn out, the current tends to jump which may cause misfire.

Hope this helps and thank you for using FixYa! Have a good one!

'83 Monte Carlo - Miss fire at idle/accel./driving


You can have car put on scope and it wll show any irregularities in the ignition system. It can also be dowithout any equipment. First, loosing ALL 8 spark plug wires, Now place the spark plug wires loosly back on, just secure enough to secure. You might need 2 people. Being the miss is more consistant in gear, APPLY THE EMERGENCY BRAKE , put trans into drive and raise rpm's till miss is obvious. Remove ONE plug wire at a time, TILL THERE IS NO DIFFERENCE IN MISS. Thats the cylinder missing. Start with the spark plug, inspect, work back to wires and cap. An EXTREME result will be NO COMPRESSION.
