Okay so I've been posting for 7 months with issues on this engine swap and it just won't end. Since my last post I've replaced the Idle Air control valve, installed a tweak'd harness, and had the ECU rebuilt by drift motion. Now the ECU helped alot of issues, the car will at least restart now but it's still doing the hunting idle and it's stuck and limp mode. I'm beginning to wonder if I might have gotten a bum IACV and was wondering how i would about testing it. Also when it does run it's running very very rich, I was wondering if perhaps this could be a problem with the crank position sensor. As always I would be grateful for any help

 

Not avoiding your question, but contact by PM QuickSc4 and Biggu. They know these motors really, really well.
