Hey I have a 1990 chevy caprice..305 that was replaced with a 350 engine thats in it now. I recently took my car to mike car shop in concord nc. And the only thing I took it there for was a tune up and for them to fix my idle control because when I use to crank my car up it would start then idle real liw then cut off. Then I would have to crank it again and give it gas for it to stay on. So when I picked up my car that was fixed but now when I come to a stop light or stop sign my car cuts off within 1 min of stopping and its never done that before.. so I took my car back then same day I picked it up and he is currently trying to fix it but I dont think he knows what he's doing because he's had my car for about a week now. Do you have any idea about what it could be?
