I have a 95 silverado that has a 5.7 tbi and the person that I bought it from put true duel exhaust on it and it doesn't have the o2 sensors on it but I have been driving it for a few years now I have a problem with it idling and then acting like it is running out of gas...I've checked almost everything except for the fuel pressure and I'm completely stumped...did anyone else have this problem if so what was your solution
