2001 Pontiac Montana - what is a misfire #5?


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.

Check engine light came on. original code


My guess is you mean misfires, not backfires. How does vehicle run when warmed up? I'm also thinking that the misfire codes are coming from a lean mixture situation. No other codes coming up either? Please reply with year, make, model, and engine, just to confirm heading etc., please.
