Question about 1997 Chrysler Concorde

1 Answer

My 1997 Chrysler Concord idles at 2500 to 3000 rpm when first started and when it warms a little it idles at 2000 rpm and stays there. When I start it right after I turn it off, it starts at 2500 rpm then quickly slows down to 1400 rpm and stays there until I turn on the air, then it idles at 900 rpm. When I start the car with the air on, it starts at 2500 rpm and quickly slows down to 900 rpm and stays there. I changed the throttle position censer and the idle slowed to 1000 rpm, but this lasted only 2 weeks. Can you help me?

Maybe a short to the TPS or something shorting it out. There's also the IAC that really controls the idle but usually it will cause the RPM's to go up and down a little erratic if bad. The MAF sensor can cause major problems as well but since you already swapped the TPS and it helped and then stopped I would focus on that sensor and especially it's wiring to and from the ECM. Be careful with the sensor signal wire to the ECM can blow it if more than 5v passes or spikes.

    I have fixed the problem by replacing the upper intake gaskets after a local repair shop applied a smoke machine to the intake to find the air leak in two cylinders on same bank.

High rpm when warming - choke problem?


It is a little high but if the ambient temperature is very low it would be ok providing you understand that there will be a bit less economy. You can fine tune the choke to drop another notch on the accelerator cam so that it would idle at say 1500rpm and the gear engagement would be less harsh

Try cleaning the throttle body plates with throttle body cleaner.Also check for vacuum leaks around the intake gaskets.You can also check for codes.Sometimes you can have codes and not get a check engine light.Hope this helps.Good luck.
