Kevin,
Awesome! I did not know you could use FD plugs in the 8?? Awesome! I have like gazzillion FD plugs at home.. Dont mind changing every 10k
I'm doing Catback replacement in next month or so.. i'll check the cat too. But I don't think its the cat.. Since the trip, Everythings been OK... No issues.
I reset the ECU by unplugging the battery, and press the brake.. I used this technique when my Acura used to have misc warning lights pop on... I think it worked on the 8 also... I think?? because I just unplugged and waited 20secs and didnt do shit! LOL!
