Car will suge and somtimes not idle properly

no its more than likely not related to the trans,if you are having shift problems though,i would have the tps(throttle position sensor) checked out.another thing to check is the vacume lines to and from the egr valve and the valve its self for proper operation.

Check your throttle body gasket, if it's leaking unmetered air it will idle high, this coupled with a bad ignition coil, plugs not properly gapped or old/worn as well as old/worn spark plug wires will cause a misfire that may not trip the CEL light. Also check your idle air control valve to ensure it's working and clean on the inside of the throttle body.

Check and repair any diagnostic codes, Clean the Throttle body and IAC unit (Idle Air Control). Check for any vacuum leaks.

check ur idle air control valve(iacv) or purge valve both affect idleing

COULD be the TPS sensor or could be more serious

idle air control motor or just a plain old vacuum leak

change the air flow meter

sound very much like a vacuum leak.... also maybe your timing is off? possibly advanced? try retarding it with the distributor if thats the case...

well there could be couple problems happened to mine only cuz the troddle position sensor wasn't working properly. so while idling the rpms would go up and down then sometime shut off eventually. but when you mean rev up and down you mean idling irregular? if so your timing belt and or pulley's worn fuel pump not delievering enuff fuel to fuel injection system, leaking egr valve, or even the air filter clogged.

ok this sounds easy when you ran the vehicle the computer controled the idiling motor now that you replace the idiling motor the computer hasnt been reset to except the new parameters
once you reset computer this should bring the idle back down to its specified idle
you can also adjust back of gas pedel the idle cable and on the throttle body by the idling screw
