Hey all, need help again!!

96 contour zetec atx 108,000 miles

car was surging and idling low when in gear at a stop, it was recommended to change the IAC which i did yesterday and the pcv valve, which was done a couple of months ago. the car is running better, but it is still fluxuation at idle while in and out of gear, more when in gear. vaccum lines are good, fuel filter is 6 months old as well as plugs and wires (oem). HELP PLEASE!!!

do you happen to have the AC or defroster on when this happens?


if so chances are you are low on r-134a and it is causing the AC system to cycle and that cuts the compressor on and off changing the idle

There is NO common problem......I spent a few days searching and testing. For me it was a faulty Accel coil AND a failling TPS. The hesitation is common the reason why is not.
