Engine Performance problem
1991 Ford F150 V8 Four Wheel Drive Automatic 140000 miles
My 1991 Ford F150 will idle extremely high sometimes and the check engine light will come on. If it's doing this when you turn the engine off it won't start up again. Somtimes I would disconnect one of the battery terminals and would be able to start it up again later. Otherwise it needs to be jumped.
What is causing the idle to be so high and would it affect the batteryr?
have the same problem?
