95 tahoe stalling

[jessezipper]

ok so its got a 231C tcase and a not stock trans. itll start in 2 of 3 gears in the tcase (assuming 2wd and 4 hi) and when brake is applied even slightly , it stalls...

this is a basket case Tahoe I just acquired. its a 4 dr 4wd,350, auto with a 10 bolt ass end.

any idea on how to fix this issue?

DO you hear a hising noise from the brake pedal area when the brake is appiled? Sounds like the power booster may be leaking. This creates a vacuum leak and creates havoc with the mass air flow sensor reading.

on the booster leaking. I had the same problem. It would stall when braking. I figured it was out of tune because of the engine swap, and after a couple days it stopped stalling, but recently it lost all brakes because the booster went out. Replaced it and the RPM's don't drop when on the brakes anymore.

nope no hissing, cant hear anything, its stalls with very light pressure applied to the brake pedal

Does it shudder and chug before it stalls?
