I

know there's probly already threads on this already but my car has been acting up lately. It runs great for about 30 minutes or so sometimes less than that but after that it just bogs down bad and has no performance but it stays running by itself and never complely dies and after you shut if off you can hear the gas in the tank bubbling. Idk If its that hot and its boiling or if its blowing air back into the tank. After the car sits for a few hours or so it runs fine again for a short period of time . I just put a new fuel pump in it and the cars has a 305tpi with 80k original miles can somebody please help me I'm going crazy trying to figure this out........also when I start it cold after a few days the idle jumps around a couple hundred rpms for a few seconds then straightens up

 

Sounds like a problem that's been covered a lot. As of yet there has been little to explain it all even though there has been people that solved their problem. https://www.thirdgen.org/forums/tpi/...-pressure.html
