1996 Chevrolet Cheyenne Repair Question
Chevrolet Cheyenne Tune up Problem
Did a tune up, now I'm still getting p0308 misfire on cylinder 8.
I pulled the plug, which I just replaced along with cap, rotor and wires to find oil along the threads, and looks worn. But it's only a few days old. Any ideas where to go. Also truck smells of burning oil, no visable leaks. 305 vortec
still 308?? you only mentioned 300 first
Start with compression test. check for spark to the plug as well
After my tune up, I've only gotten a p0308
ok, is the plug gap correct??
Gapped to .06
I can wipe oil off the threads. Is that a sign of a leaky valve gasket?
most likely. is it leaking from the valve cover>????
Honestly Roy, I'm not sure how to tell..
