Possible water issue there also with both of you running through the car wash pcm might have gotten water on the connection, possibly frieing the pcm.
interesting theory....mine is just kinda chillin there since I have a cai but I figured it was a sealed connection like most. Any way to tes it? And if it was fried wouldnt the car not run ya would think?
