I have a 94 Chevy K1500 5.7L V8 w/TBI throttle body. It stalls out on me while on idle. I’ve changed out the Idle Air Control Valve, I changed out the Mass Air flow sensor, the purge valve sensor, the throttle position sensor. It has no air leaks, I change out all the hoses to be sure. I changed the distributor cap and rotor, spark plugs and wires.

vacuum leaks don't just come from hoses. It could be manifold, vacuum tank, valves, AC unit, etc.
