1992 Pontiac Grand Am 4 cyl
Cylinder 3 is not firing. Already checked fuel injectors. Yet when in passing gear, it seems to operate normally. Changed plugs, no improvement. Next step is to see if plus is actually firing. Do you have any other thoughts.
Originally, last week, I asked the question about a 1992 GrandAm with a cylinder not firing. Mechanic responded that I should check the coil pack which I
did. I now believe I have an intake valve stuck open. How do I check for sure. Compression test, maybe?
have the same problem?
