KA24DE

Its a new swap, never ran this motor. Fires up and runs great with MAF disconnected. When MAF is plugged in will die/ or try to die, have to pump the throttle to keep it going. Once it reaches 2500 rpm or so revs normal. I have tried 2 other known good MAF's with the same result. I have checked the usual suspects, vacuum leaks, Dirty/bad IACV. No vacuum leaks to be found, removed and cleaned IACV. Gonna try a coolant temp sensor tommorow. But don't think that will resolve the problem. I have used the SEARCH, but only to find similiar threads with no resolve. Anyone got some info?
