Finished putting my new 22re long block together two weeks ago. Working on setting it up and test driving. One of the few things that is not brand new is the throttle body and intake, so there are some question marks in that area. I have set the Tps twice, once when it was nice and accessible, and then again yesterday on the truck. I think it is set right. Warmed the truck up and set the timing as stated in the FSM. Seemed to go exactly as it always does. Double checked the vacuum hoses. They seem correct, but a bit tricky with black hoses against a black truck. Was going to test drive, but rpms won't go past 2000, without a high surging idle occurring. Haven't had this before, so any pointers are welcome. Anything simple I might have missed? Before I pull off various parts from the other engine, which had no issues like this. I have 3 throttle bodies, but no O-ring for the aux idle valve, so I could just swap out throttle bodies. No check engine, sparks and wires are brand new, cap and rotor new, etc.
