I have a lumina that I use for going back and forth to work in. I have had an issue with it when it gets cold outside, and have been told that the computer has had issues in the past. If I track down all other problems and find out that the computer is at fault, is it an item that I can just be reflashed with the oem file? Is there a tester that I can use that would for sure point me in the direction of the problem. I would really love to get this thing reliable so I can put the Suburban in the shop and start on it full bore. I didn't drive it home, it didn't want to cooperate to get home so I drove one of the pool cars home. I have never thought of doing any tuning on it, but I guess I am wondering if my hobby could be a possible repair for this car.

Its a 93 lumina with the 3.1, I don't remember if it has single or dual cams in it. Does anyone even have the files for something like this?

Thanks guys, I really am learning on the fly!!!
