Anybody tell me if you have this problem: I had my toyomoto headers installed today and for some reason my check engine light was flashing when the car was idleing(car was idleing real weird like!!!), then the check engine light stayed on and the trac off censor started flashing. Now at first I would think human error but the mechanic is one of the best I have had working on my cars. If anybody got any ideas as 2 what the h%ll is going on it would be greatly appreciated.
