1996 2500 360. Start and runs. Acts like it won’t take fuel sometimes when you hit the gas. Cuts out very often until it warms up. I’ve heard a number of things. Haven’t gotten to take the throttle body off and clean it yet. Supposed to be freshly rebuilt and all sensors look new ( I know that doesn’t mean anything one of them still could be bad) but thought maybe this could be a vacuum leak??

 

Possibly. Are you getting any codes? Last time the truck had a tuneup? How old are the O2 sensors?

 

02 sensors have been checked. Plug and wires are brand new. Oil change also not even 500 miles ago. If that. This 360 has supposedly been rebuilt. Which you can see fresh paint and new manifold gaskets. But who knows how true this is. And haven’t checked codes lately. But when I did check it was something to do with where it’s been swapped to 5 speed and it was erased. Just had some stuff stolen from me and code reader was one.. This truck is kinda like Frankenstein. Little rough around the edges. Lol.

 

Might wanna check fuel pressure.
