2002 Ford F-150 runs rough and smokes blue out the drivers side exhaust.
Truck: 2002 Ford F-150 4WD 5.4L XLT
My concerns:
Runs rough (Shakes at low RPMs).
Clicking noise at above 1000 RPMS.
Smokes blue out of the drivers side exhaust.
The oil is clear.
The coolant does not have oil in it.
I just replaced all of the spark plugs. The threads on all 8 had oil and water
(not sure if it was coolant) on them.
OBDII shows code: P1151
Any help would be great!
