Engine Performance problem
2002 Ford F150 6 cyl Two Wheel Drive Automatic 99,210 miles
My truck has thrown these codes: P1131, P1151, P1071, P1074.
I have replaced the MAS, fuel filter, air filter and light came back on.
I have checked for vacume leaks 4 or 5 times and cant find one.
Yesterday the truck started to miss out on the way home from work in OD. Got home started checking things out and noticed when in drive and the engine is under a load between 1500-1900 RPMS it starts to miss. Could this be a bad injector or coil issue?
have the same problem?
