Last saturday i had best buy install a new sound system. All alpine, 2 6" type R's in the front, 2 12" type R sub's in the back, 2 V12 amps and cap for the sub's. A new alpine head unit and XM radio. As i'm leaving best buy the CEL is on. I turned around and asked them about it and they have no clue. I end up taking it to toyota service on monday and takes them 2 days to figure out that my ECU is bad. At the moment my car only has 380miles on it I've had it for a bit more then a week. So my big question is could best buy have done something that ruined my ECU?If so when i get my car back from toyota (at the end of next week)could this audio set up or something they did cause it to crap out again? Only other mod i have is the twm short shifter and i doubt that could have caused it.
