Hey guys I have a 91 se-r motor in my 200sx se-r. Ever since the swap my Idle has been all messed up and my engine light came on too. I replace the Idle control valve the other day and the problem still occurs. I was wondering if any of you guys have any idea's. Thanks

I think I might be having the same problem as you. I have cold idle issues with my new DET(car wants to cut off on a cold starts) and it idles at 1400 rpm when its warm. I'll be changing the air regulator in a few days to see how things go. I'll let u know if I progress.
good luck,
Nick
