Put new coils on right hand bank!! Coil # 3 was hard the get out of the head!!! And Looks like It Kinda exploded inside???? Same Codes before and after coil replacement!! Any Ideas?????? 100,000 miles

Maybe a silly question but did you clear the codes with the generic code reader or are you thinking they would just clear themselves? Most Generic code readers will clear the codes, I think the codes might automatically clear if you drive it for a few miles without the computer sensing the fault anymore, at least for the check engine light, but the code will probably be locked in the ECU until cleared.

Yes I Did Twice! The Same result!!

Did It Kill The ECM??? Or Is The Wiring. Did The Water Pipes 200 Miles ago Starter Too!Everthing feel right into place!!!
