Low Idle of a '02 ST

[Corwyn Moores]

I have a 2002 ST that I've had since new. Lately it has had a low RPM at idle problem. The RPM's at idle drop to about 450 or 500. The confusing thing is the truck normally idles smooth, no sputtering but every so often the RPM's drop just a little to low and stalls the engine.



I already ran the IAC diagnostic and cleaned it up but all was OK.



Has anyone else had this problem?



Thanks

Some have run into dirty throttle bodies or dirty Maf's...



Clean both of them, and check your air and fuel filters as well...

Guess I know what I'm up to next weekend.
