Question about 1988 Ford F 150
F150 5.0 wont come off fast idle check engine lite will blink once in a wile when enige is cold
Check the temp control switch behind the thermostat, but more than likely is an air leak in the plenum gasket on the intake where the plenum connects onto the intake, this is a common problem , when the gasket gets a leak the air fuel mixture is messed up and the computer will try to compensate for the lean mixture and add fuel therefore increasing rpms.
