Jeez, why was the very first reply not "what are the codes"??? Engine light on, not running right. That means the codes will likely fix your problem. Take a paper clip and short pins A and B in the diag port under the dash under the steering wheel. turn key on (not start), watch the engine light blink. The sequence tells you the code. Each is repeated 3x. Watch for ALL of them. Post them, I will tell you how to fix it.
This sounds like either a IAC circuit issue or TPS issue. The 400 is actually a 4L80 or 400 with OD. Solid trans with manual TV cable. Later models are 4L80E with full electric valve body. This truck should be stupid simple to fix. Never had a TBI chevy beat me.
Please understand this. This trans uses a eletronic TC lockup. It reads TPS to determine that value. TPS screws up, TC tries to lock, engine stalls like you dumped the clutch with no go pedal. GET THE CODES
