My son came home from college for thanksgiving and after I asked him if the truck was running ok... he said, Oh yeah, i was gonna tell ya, it has been running bad and says check engine. Geez...
I went to Autozone and it said the cam position sensor was bad and # 5 cylinder was misfiring. Along with an EVAP issue.
It is a 2002 F150 with the 4.6 engine. Had OEM platinum plugs and coils replaced 60K miles ago. Truck has 153K miles on it.
I ended up taking him back to school as I thought I had it corrected, but nope...
after the autozone Cam position sensor along with a coil did not fix the issue I got a ford OEM cam sensor. helped a lot. now to my delima...
It starts fine and idles fine. At about 45 MPH and RPM of about 12-1300...if I accelerate gently, it misfires quite a bit. If i give it enough gas to downshift and raise RPM to 2000, runs smooth as can be...... WHY ? bad plug?
I disconnected the battery to clear the codes and check engine light is not on anymore. IDEAS ???
thanx,
