My wife put gas in our 2005 dodge grand caravan. Not long after the engine started sputtering. I ran the codes and pulled p0202 and p0302. Any ideas what is wrong? Fuel injector maybe?
Practically nill. A faulty injector can flag both codes as stated in the links. Check injector pulse using a noid light you can sign out from AutoZone or the like for a deposit. If it doesn't light up you may have an open wire, poor connection or faulty PCM.
Before i even had a chance to look at it, im now getting error code p0300, which i believe is multiple cylinder misfire. Any ideas what to look for now. or should i just start changing plugs and go from there?
