heavy missfire 1990 740 16 valve
My 1990 740 16 valve started to missfire terribly all of a sudden.
The head gasket was replaced 1,500 miles before this due to leaking oil into the coolant. A shop did the work. Did NOT mill the head; said it was unnecessary.
Removing the plug wires from the forward two cylinders actually makes the engine run smoother.
timing / balance shaft belts checked OK
Compression checked OK
What is going on??
The shop can't figure it out.
