Ok guys first off I wanted to say a big thank you to this forum. I have been building my project for the past few years and this forum has been gold. This is my first post because there is so much knowledge in hear that all I have needed is the search button. Alas I am at a point I could use some help.

My car is running but won't idle well at all. I have to give it some pedal to keep it going and it won't idle below 800 very well. It wants to die below that. Runs very rich. Here is my setup so you know what you are working with. I won't list everything but the stuff that should matter

1996 S14.5
RB20DET stroked to 2.2 fully rebuilt
RC650 injectors
Q45 Maf and TB
Power FC (injectors set to 37% with no latency correction and air to the 90mm option) other than that it is set to stock for now.
No AAC or IAC or any other smog options (I'm open to putting this one but would need some guidance)
Greedy knockoff intake but not crap one
Top mount GT3071R
Wiring Specialties Harness
Tomei Poncams or Procams (been a while haha and can't remember ATM)
Solid Tomei lifters and stiff springs
Adjustable Tomei Cam Gears
Supra fuel pump 2jz
3" Tanabe turbo back exhaust

Thanks for any help. I am hoping to have a wide band tomorrow

P.S. I live in Denver if anyone wants to come over. I'll provide the beer and food.
