Engine Performance problem
2002 Ford Festiva 4 cyl Front Wheel Drive Automatic 113K miles
I recently asked for advice re this prob on yr site, and paid my contribution. You suggested check the IAC valve if may have to be cleaned. This had been done to no avail. Mechanic replaced the computer (located drivers side near ankle area) Still making no difference.
Makesno diff if engine hot or cold. Any further suggestions please.
