I am sure someone has done some sort of write up on this but I need help as soon as possible. I got the 84 laser running, but now she wont idle. I checked all the vacuum lines and ran them the way they are supposed to be ran but now she does not idle at all. I will start it up and it will just die if I am not on the pedal just a little bit to keep the rpm up. also she stutters and backfires at low rpm until about 4000.
