haven't had a chance to look at anything yet due to weather but the other day i was driving and my passenger side controls crapped out on me. power window and locks don't work from driver or passenger side. driver side control works just nor for passenger side. then when i started it up yesterday to see if by some odd chance it would work, maybe a lose connection or something, i got a bunch of warnings on my dash. decreased engine power, check tire pressure and service engine soon. seems like the computer had a seizure. anyone ever have this or know what needs to be done?
01 coupe. i have had it for a year and a half and i haven't done anything to it. far as i can tell all it has aftermarket is exhaust and air intake. oh sorry i did put a cd stereo in a few months after i first got it but it was a stock stereo all plug and play nothing unusual happened and it has been fine for a year or so.
