Have to get this beast smogged so figured I would change the plugs and clean the throttle body. Disconnected the battery, put 41-103's in it and then went about cleaning the throttle body. Connected the battery started it back up and noticed a miss. Thought maybe it was the computer relearning but nope. Shut it off, tore it back open thinking maybe a vacuum leak but everything looked good. Cleared the P300 then went to put gas in it and finally the engine light came on. Got home, scanned again and thats when it gave me the P303.
I know coils don't usually go bad just like that. Is there anything wrong with an aftermarket coil?
