Question about 2001 Pontiac Montana
2001 Pontiac Montana - what is a misfire # 5? My mechanic has changed the spark plugs, fuel tank, wire set and coil. But it's still running rough when it first starts (shakes - like it's going to stall, although it doesn't) and the check engine light goes on.
Without your actual trouble code, I am assuming that you are have a misfire on cylinder # 5. The computer cannot really tell what is causing the misfire only that cyl 5 is not putting out full power. If it misfires when cold then smooths out as it warms up, I would say it is probably an injector that is sticky, as it warms up it starts working properly.
