2004 Chevrolet Colorado Q&A
2004 Chevrolet Colorado Question: My 04 L5 Colorado is showing a misfire code.
What is the code number? Anyting other than random misfire code PO300, the last number in the code is the misfiring cylinder. Example: code PO 305 is a misfire in cyl 5, code PO 302 is a misfire in cyl 2 etc.! MOST LIKELY SUSPECT: a coil is breaking down, suggest replacing ALL coils and plugs! Also suggest using ACDelco parts, if you plan on keeping the truck! However @ 142k whatever. - pushrod
