I have an engine misfire and other codes out of the blue. My check engine light had gone on steady after fuel fill (not proper grade) and when out. Came back on steady for a couple weeks. It started flashing and stopped after a couple min. I took it to the mechanic and he checked the codes and stated there were a lot of codes posted and they are pointing to a misfire and possible leaking fuel injector. I've read that there could be a faulty ground causes this? anyone aware of this same issue and fix? My car is headed back to the garage after a $250 tow to replace the injector at $1000. I obviously don't want to initiate this fix if there is something simpler like a ground wire causing this. Never had any issues like with this this car ever.
