sr20det idling problems
 

Okay so I recently swapped my ka24e with an sr20det redtop. The second day I had it I was being a dumbass and could stand not to keep my foot out of it and rsced a corvette on the freeway. I spun 2 bearings and ruined my camshaft so the motor had to be partially rebuilt. Anyways. I get the car back from the shop and it starts idling funny. It will stay at 1500 rpm (im guessing thats normal?) For a while then it will start to sputter and die. But it never really dies. Th rpms even get as low as 300. Since the computer is still trying to adjust and get to relarn the car is that normal or do I have a problem? Please help. Thanks guys.
