Black plugs after head gasket
First post here, but not new to forums or wrenching. I searched this forum but didn't find any answers so here's the background:
'98 CL 2.3 came to me with a bad head gasket. After finding the head not warped using a machinist straight edge, I put the engine back together. started it up and it ran real rough and stuttered real bad if you tried to accelerate. Pulled the brand new plugs and they were covered in black soot indicating a real rich mixture.
I have verified the following: 175-180 PSI in all cylinders, cam timing is dead on, no adjustment for ign timing, valves are set .010in and .012ex. NO CEL and I am lost. Nothing that I can see disconnected, swapping back in the old rotor, cap and plugs made no difference. Any ideas? thanks for any help.
