To all who tried to help me the problem is solved. It was what I thought the whole time. Computer was taken back out and sent back to the rebuilders and they found problems with their work. I drove it until the weather turned bad in Virginia and it had gotten to the point that it would cut off at stop lights. No more choking at 3500 RPMS and no more cutting off at stop lights. Only problem now is an old one where I smell raw gas around the fuel tank fill. Cap was replaced and I see no gas on the pavement or car. Maybe one of the boots on the fill tube???????
