Hi....I was wandering if anyone could help me out on a problem I'm facing with my Impala 96. I installed a headman hedders after I did the car started to backfire and choke! It happens when the car start to get warm, but when its cold it runs fine. I thought first it might be from the distributor because it showed-up on a computer test to be weak, but nothing changed. I also checked the fuel pressure and found it ok. I hope that you might have some idea of what might the problem be. Looking forward to hearing from you soon.
Thank you? A Al-Adsani
