88 4x4 Burb 1/2 ton. 350/700/208. Runs fine when cold, but keeps stalling out when the engine is hot. Idles ok but the second I touch the go pedal it stalls. Dumping too much gas into the TBI. I can sit and watch it pool up when the engine quits. When I start it back up, lots of black smoke and reeks of gas. I've already checked the EGR, PCV and the entire TBI unit. I took the belt off the smog pump (AIR system) and at least now it will start when flooded. Any help will be much appreciated.
