Engine Mechanical problem
1998 Dodge Ram V8 Four Wheel Drive Automatic 86,000 miles
When accelerating, the engine has a lean pinging sound, then the "check engine" light comes on.
The computer scan says "MISFIRE CYLINDER EIGHT"
I did a compression test on that cylinder and it was fine. The plugs are new.
I have replaced the cat converter, plenum pan gasket, wires, cap, and rotor.
Can it be the PCM? I read that there is an older TSB regarding reprogramming the PCM for these symtoms.
I neglected to mention that I also pulled the injector and the screen was free from any debris.
Although, the schrader valve on the fuel rail blew out a foamy, bubbly fuel when I depressed the stem. Is this normal? Or is it part of my problem?
have the same problem?
