Ok I think i have tried everything with my rough idel.My 95 tour atx runs great with a little hestation but at a stop(idel) it seem to run a low rpm real low where is stall.Now this weekend I Replace the IAC,

I have also previously replace the wire and plu, clean the EGR, clean the MAF,replace the motor oil and trans oil and I have no cel lights going off what can it be. Can the ignition coil be the problem?
