I'm having problems with my '95 Contour (V6, 5 Speed) where it will not idle properly, but drives fine otherwise. When idling it might run fine for a few seconds, then the revs drop, and about half the time the engine stalls..
This problem started about a week and a half ago, and I thought that I had it licked.. I cleaned the IAC, replaced the EGR valve, replaced the PCV valve, and still no joy. Then I cleaned the MAF, and everything was good for a few days/hundred KMs, but now the exact same problem is back.
I tried cleaning the MAF again, but the car still won't idle. If you unplug the MAF, the car runs fine, but with a higher than normal idle (exactly the same as it did a week before). The MAF tests fine using a multimeter, and the car throws no codes..
Since the MAF is clean, and it was working fine, could the MAF simply be shot now? Could it be a problem with the temperature thing that goes into the airbox?
What's the next step that I should be taking?
