I replaced my t-body with a remanufactured one in my 95 Chevy Truck(350, 5.7L). Before i replaced it, i was experiencing rough idle when the a/c was on peridiocally. I was going to to replace the IAC valve but decided to replace the entire t-body. Since doing that, I've experienced stalling out after the engine idles down and also stalling in acceleration meaning if i'm up to speed and let off the gas for a second and then give it gas, it stalls and kicks back in up to speed. What could be causing this?

Sounds like a gasket leaking vacuum.

Also check the setting for the TPS (Throttle Position Sensor).

I installed the old one back on and it's running fine. I'm going to have the new one tested. Question, could my fuel pump be weak? I don't understand how the old one works and the new one has problems.

between stickman and tailpipe, you'll probably find your answer.
i never see these damn things before i get to hazard a guess no one else has.

Returned part and found it to have a crack in the body. Anyway, returned it and it works fine.
