Could it be the injectors leaking? Anyone else have any ideas? It almost sounds like HITHERE sensor is getting hot and not working correctly. HITHERE don't know on this one. Sorry HITHERE can't help more.

You may also have an FPR that's leaking through the diaphragm and flooding the plenum. It's easy to check by removing and capping the vacuum hose while watching for fuel spillage out the regulator hose bibb.
