White smoke after start up????HELP!!
Guys, for the last couple of weeks i have noticed that sometimes when i start my truck it blows white-ish grey smoke. If i rev it a little black smoke will mix in. After driving it for little it just stops
It doesnt seem to effect the performance so not sure whats going on. I did check the DTCs and it had a P1635 GM: 5 volt reference Circuit. I cleared it and drove it home and the same code came back. Any thoughts??
