Question about 1991 Plymouth Acclaim

1 Answer

We have a 91 Plymouth Acclaim 6 cyl. The car runs well when at speed but it randomly stalls out at idle. It will also stall randomly when slowing down to stop in traffic. Any ideas what it might be?

Remove the A.I.S motor and give it a good cleaning (especially the pintle -pointed end ) with throttle body spray cleaner, as well as the port you remove it from, then re-install and try it. That will usually cure it, and if it starts to happen again, replace the A.I.S. motor. Doesn't hurt to give throttle plate and area a spray while your at it.We have a 91 Plymouth - fd70c70.gif

    Ok - I got all the parts identified now how do I remove the AIS? (If you gather I am a novice at this stuff you are right - but right now I can't afford to pay the shop to fix this). Thank you for your help!

    Remove electrical connector obviously, then remove the 2 (usually ) torx head screws, and wiggle it out of the hole. Pay attention to how it was lined up for re-install. Careful not to lose small "O" ring. Clean it as described, and rub a little vaseline or clear type grease around "O" ring area and re-insert it after cleaning hole out with spray as well.

Car stalls then restarts

You need to run a fault code test on the car and do the service below. To run the test follow the instructions HERE
Also do this service.

Engine stall or RPM fluctuates at idle.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

My son's 92 Plymouth Acclaim, occasionally sputters when approaching a stop & stalls when completely stopped. A previous owner set the idle speed pretty high apparently to try to correct. ...

Hello -- It could be what's called an IAC (idle air control valve) -- if it is acting up while running vehicle prior to operating temperature.The speed sensor would be more in tune with making the speedometer read how fast you are traveling. You could check the haynes or chiltons repair manual at your local library - call ahead to be sure of availability, alternatively most auto parts store have them for like $20 - again call ahead for availability.

I have a 1994 acclaim with a v6 it will stall when coming to a stop or just at idle in park

Try removing the idle air control motor (IAC, or AIS ) Automatic idle speed motor, same thing.Spray the pintle (pointed part) and port it was removed from with throttle body spray cleaner until clean and re-install and try it. Don't push or pull on shaft or pintle, just clean it and re-install as it was. If it works for a while then starts to do it again, replace it.

I'd pull the AIS motor ( automatic idle speed ) of side of throttle body and give it and the port it comes out of a good spray of throttle body cleaner, especially the Pintle ( pointed part) and re-install it and try it. If it cures it great, and if it starts to act up again a while down the road, replace it. Also referred to as IAC sometimes.( automatic idle control)

One suggestion:
Speed sensor failure.

Some of the classic symptoms, stalling at dead stops. failure to auto lock doors. poor fuel economy. Failure to go to overdrive.

Go to your local parts store and run the failure codes.

Shop notes:
Your ECU thinks that the engine is running with out moving, During slow down the engine steps down the idle to match ground speed and as a result the engine will not stall. At present it goes directly to idle and stalls due to drag on motor.
Hope this tip helps.

Car idles, starts just fine but when I shift into gear it stalls.

It sounds like the kick down cable or "down shift cable" This is the cable on the transmission that shifts back down when the car slows. The transmission is most likely stuck in a higher gear and simply stalls the engine when shifted. replace this and i believe you will be back on the road. Hope this helps. Good luck.
