Re: Issue with idle after tune
Does the CE light still come on? I so what code is shown?
I know this is a bit out there but on one of my LS swaps the 12 volt constant connection at the fuse block was bad. Mine did a similar thing as yours. On cold start it was fine. Then if I shut it off for a short time it would stumble and not not idle correctly for 20-30 seconds. Finally the connection failed and left me on the side of the road. Found the problem by smelling the melted plastic in the fuse block.
