I switched from a 2bl to a 4bl and started having trouble with car idling high and when I come to stop or turn the car turns off. So I went back to the 2bl thinking that this would solve the problem bc I did not have this issue with 2bl. Now that I switched back to the 2bl I still have a high idle and car shuts off when I’m coming to a stop. If I switch the gear to neutral as I come to a stop the car will continue to run. Just hoping to get some ideas or I need to find a new mechanic.
What 4 bbl did you use? Make sure you didn't create a vacuum leak while working on the car. You did change the intake manifold, correct?
