Question about 1998 Plymouth Neon

1 Answer

Engine Turns Off when running AC

When I'm running my AC and coming to a stop, my RPMs are reduced to nothing and the engine comes to a stop. I have to turn the car back on and keep my foot on the accelerator to keep the engine from dying. Sometimes the RPMs will dip, but come back up, especially when I'm moving slowly. It rarely happens when I'm not running my AC, but it has happened. I have a 5 speed with a DOHC.

Your throttle speed sensor(idle speed sensor)is not working properly.It's job is to keep the the engine at the proper rpm range when you are not applying the gas peddle.This is the most likely cause.

AC blowing only hot air. How can I tell if it is the comprosser and just needs recharged?


When the engine is running, turn the AC on and watch the tachometer if you see the RPMs dip slightly then the compressor is kicking on. You should also be able to hear a new sound coming from the engine (do this with the hood lifted).

If you hear it come on and see the RPMs dip slightly, then the compressor is probably still good and it just needs to be re-charged.

My '99 Saturn SL Check Engine light turns on constantly. It sounds like it wants to stall when I come to a stop. Also, if I turn on the ac, the rpms don't stay steady. Could it be my transmission?


something in the air fuel management. check the hose from the air cleaner to the throttle body.there is a sensor on that hose,that if the seal is no good,will cause idling and running problems.

2000 isuzu rodeo check engine light flashes when at or around 2500 rpm and up. engine runs smooth and no codes come up ? light goes out when rpm is reduced.


are you checking code with a small simple scanner this will not always work, a larger more sophisticated unit may find code or runs codes at over 2500 rpms when light comes on

check all vacuum hoses.if any looks cracked replace them.make sure carburater bolts are tight.check the egr valve make sure its not leaking.besure have your idle speed adjusted.it should be at 550 to 600 rpms.

AC blows cold while moving, and gets warmer while I'm stopped


There are two fans behind the radiator. One is suppose to begin running when the AC is turned on. The other is to cool the radiator when it gets too warm. Raise the hood with the engine running and AC "on"and see if at least one fan is running.

Rpms fluctuate


You are running LEAN. Meaning it could be a number of possible problems. Most likely cause is a air pressure leak. Go to your local auto parts store and buy some carb cleaner. Run the car and spray into engine compartment. If you hear the engine RPMs go up then you've found your leak.
Do you have a check engine light ?

Engine runs rough after about ten minutes /idles really low


Just trowing some suggestions out there, but, I would check the idle air control valve (solenoid) or the throttle position sensor. If they check out then my last guess would be the map sensor or the vaccuum to the map sensor. Hope I was able to help. Best wishes.

Cooling fans will only turn on if engine is off only


Electric cooling fans do not run all the time. They will only come on if the engine exceeds normal operating temp. Also will run when AC is on. Easiest way to make sure they are operating properly is to first verify they run when the AC is on. Next turn the AC off and run the engine at 2500 rpms sitting still and monitor the temp gauge (don't let it get into the red). The fans should come on after 10-20 minutes (depending on outside temp.). As the engine cools down they will turn off.
