Idle runs too high when I come to a stop, for about 5 seconds.

My 1999 SL1 idles high when I start it for about 10 or 15 seconds before it slows down to normal, and also when I stop.

The throttle body may need to be cleaned. Take off the induction hose to the throttle and open the plate. Make sure the vehicle is not running. With the throttle plate wide open, soak a cloth rag with carb and choke cleaner and work the rag around the inside of the body especially where the plate's closed position is. remove the rag and spray a small amount of carb cleaner down the throat of the throttle body. replace hose and run vehicle at 1500 rpm's for a few seconds. This should fix the idle. It should be idling at about 800 rpms.

It sounds like an automatic choke. Let it warm up a bit.

When I slow down to a complete stop, my 1999 chrysler sebring cuts off. Can you help me?


Possibly a transmission issue. The transmission has a "lockup" mode, where a clutch connects the engine directly to the transmission at cruising speeds. It is then supposed to unlock at lower speeds and for stopping. If it doesn't unlock, the car will stall at a stop. Try putting it into neutral (carefullly, so you don't go into reverse) as you slow down, if it doesn't stall out, it is most likely the transmission lockup mechanism.

If it stalls in neutral it is an engine issue. Bad idle control, bad ignition (it's easier to fire at high speed), bad fuel injector, bad air flow/pressure sensor... and more possibilities.
