Truck has codes PO132 for the O2 sensor high voltage, PO300 multi-cylinder misfire, and PO301 Cylinder 1 misfire. I think cylinder 3 is misfiring as well but it didn't spit a code for that. Game plan is to replace the O2 sensor and change ignition coils as well as spark plugs. Is this the right coarse of action and should I check the fuel injectors as well?
