Rough idle and stalls at stops runs fine over 1000 rpm already tried fuel filter and fuel addative.

Dirty air filter, dirty throttle body...try 2 bottles of gas line fuel injector cleaner...has your car been parked for awhile? Heet gas additive will work on any low gas tank sludge that you may have. Hope this helps.

This could be a lot of things. one of the tests that you need to run is shift it into nuetral when you are stopping and see if it still drops RPM and wants to stall. This will eliminate or conclude that it is a transmission issue. If it is still doing this then it could be a vacuum leak or fuel delivery issue.

Common problems
1. fuel filter clog and fuel pump stop working
2. Crankshaft sensor (spark is cut during high demand)
3. Air filter clog (not enough air during high rpm
hope it helps

Clean the throttle body and check or replace the idle control valve. Also check or test the throttle position sensor.

the distributer cap is probly worn-inspect--throttle body may need cleanin/also idle air contol/egr valve--get vehicle scanned its an OBD I system

HI,have you check fuel filter fuel pump pressure

Try changing the map sensor it controls idle and it could affect your car like that...........

start by pulling hose off egr valve see if idles smoother almost instantly

check your transmission fluid,the motor will stall when fluid is low

hello first check your idle with the car running foot on brake see were your rpm reading is if your below 500rpm check your label underhood for your curb idle setting second see if theres a adjustment screw you can increase were your gas cable lever rest against your set screw underhood if you feel confident enough remove your iac motor idle air control valve if the bore were the end of the pintle extracts out to close has varnish builup our carbon it will stick creating vacuum leak type senario causing stalling rough idle sometimes even no start conditions good luck
