[QUOTE="Kelly Adams, post: 436818, member: 21298"] Firstly ... I shall conclude that your mechanic confirmed no evidence of a poor/bad/broken connection in your ignition system ... especially cyl 3. I also doubt that both electrical and fuel problems are "happening" at the same time ... in the same hole. I suggest that you switch cyl 3 coil with another. If the new fault code(s) are still cyl 3 ... switch plug 3 with another. If the new code(s) are still cyl 3 ... you can now focus on "fuel" ... which could still be an electrical problem ... like the connection to #3 injector. Kelly Adams [/QUOTE]
