What's a computer box? You're going to have to take it someone and have them look at it. You must have a check engine light on? What are the codes?
Well I was told the computer box is the brains for the whole car. It is electrical problem. I dont recall any codes being displayed. I have someone looking at it now. It is at a shop where I have taken a few of my cars before. He reall doesnt know what is wrong with the car. It was his diagnosis that told me to get a computer box, and now I have spent all this money and the car still runs rough and very hard. Do you have any suggestions? I do remember when I bought the car, the engine light was on, and I took it to this shop, where I have it now. He said there wasnt anything wrong, and now years later, he doesnt know what is wrong with the car. He has my car now.
