Hello all, I just had an aftermarket stereo installed in my GN and when I was driving home, the service engine light came on. I took it to my buddy who scanned it and it came up CODE 42. It says that the computer is in "LIMP HOME MODE". Ever heard of this? It lists 4 reasons, most had to do with spark, or spark control. It listed coil pac, ecu, etc. Has anyone ever seen this before? I noticed that the stereo guy run the amp wire inside the car right close to the computer. I am going to start with plugs and wires, what else???I need some BUICK EXPERTISE!!!
