1992 engine mis fire
Colorado has an emission inspection that the car failed. High CO
.I took the car to a local repair shop today and had the spark plugs replaced. Number four spark plug was fouled. As I drove off the mis fire was still there.
Any ideas on what to try next ? Plug wires? SHOULD i GET THE $100 engine diagnostics?
Thanks for any help..
