I have the truck listed above k1500 4x4 v8. When it gets warmed up and I come to a stop, I take my foot off of the gas and it starts to stall when I tap the brake it smooths out. I changed the IAC valve, the TPS, the coolant temperature switch, but there are no check engine lights. could the problem be the lack of O2 sensors? when I bought the truck it had straight pipes so i put a muffler on to give the engine back pressure. I took off the throttle body and got a rebuild kit and cleaned the heck out of it replacing all of the gaskets. i am at a loss for words. any more ideas?
