1997 Ford F-150 XLT 8 Cyl 4.6L
eng runs rough and misfires only at operating temp. this vehicle has no carb and im thinking about the air flow sensor?
this problem happens mostley at idle and moderate speed if i gun the eng it seems to run better, but always when the eng is warm never when its cold. at operating temp the eng even fail to start untill it cools down.
