Engine Performance problem
2002 Ford Ranger 6 cyl Two Wheel Drive Manual 140000 miles
Intermittantly when I push in the clutch coming to a stop the truck goes to nearly 3,000 rpm at idle. Turning the a/c on or loading and unloading the engine with the clutch will usually drop the idle to near normal.
I haven't seen the check engine light come on.
I tried physically putting my foot under the gas pedal and pulling up. No help.
Last time I wrote the truck had a terrible spark knock. 2cars recomended I clean the MAF with MAF cleaner. I did that and it seemed to help for a few days but the spark knock is back.
