2004 Chevy Express V8 Two Wheel Drive Automatic 339000 miles

I have a 2004 chevy express 6.0 v-8 the van starts fine runs fine until u turn it off when you restart the van it runs bad and does not want to go seems like it want to stall out, but if I play with the gas pedal I hear a pop/tap noise and the van runs great then after a few red lights it starts to run rough again.

I also can turn the van off and restart it and it will run fine.

I have replace the cam sensor, plugs, wires, cleaned the throttle body, check for vac leaks, new alternator / battery, new throttle body gasket, checked the valve springs (none are broken).

No check engine

A couple things. First, have you checked the EGR to make sure it isn't carboned shut? Also, the intake could be carboned inside where the EGR mounts. Check that and clean it out if it is.

Finally, with that many miles, have you checked compression?
