Turbo convertible won't idle!!
Dear rotory gods,
I need some help. I just finished putting a s4 13B-T into my 88 convertible, but the car won't stay running. The car will fire up and stay on if I keep it above 3000, but it won't even come close to idling. The car is running super rich according to my A/F ratio guage, and it backfires frequently. I have all of the emmisions removed as well as the BAC and the AWS. I am SURE that I don't have a vacum leak, and the ecu is not spitting any codes. What could be keeping my car from idling?
I need suggestions on other things to check.
Things I have already checked for:
1) error codes from the ECU, I spit out one, but I fixed it and I still wont run.
2) cracks in the TID
3) vacum leaks on the manifolds.
4) vacum leaks on the throttle body after doing the throttle body mod.
5) Whether both primary injectors were opening.
6) Fuel pressure
7) Spark plugs
8) Coils
My latest idea.
What do you guys think about this? Is it likely that not having a fuel pump resistor could be causing my car to run so rich? How about a bad fpr?
Please help me out guys!!! I want to get this bad boy on the streets ASAP.

Have you checked the timing and the TPS? Honestly, the same thing happened when I did my TII swap and it was a combo of a cracked TID, vacuum leaks, and the TPS. How did you check for vacuum leaks?

have you adjusted the idle control on the back side of the tb? you know the one that is like a 8mm nut and you can use a small *** screw driver to adjust it to where you want. i had the same problem for like 3 or 4 days until i tried that out.

Thanks for the ideas guys. I checked for vacuum leaks pretty well, my boost gauge also reads about -20mm Hg, I also have checked my TID for cracks. I'll check the timing and the throttle control screw tomorrow.
Any other suggestions/ idea on things to check?
