Author Topic: 89 mustang won't run good cvr 5.0 ¯ Member # 2962 posted                              It ran fine last night when i drove to a friend's house, but when i went to start it, the car started to surge. I thought it was okay because it was very cold out, but every light i stopped at, the car wanted to die, so i had to give it gas to keep it running. I started it up this moringing after i cleared the computer and checked the conections, and all it does is surge bad and quit, and i haven't touched it under the hood for a while and i do not know what it is.HELP!!!!!!!!!!
