Basically, above 1200ish RPM it runs great as far as I can tell (I can't actually drive it cause of the idle problems) Fuel looks good, it bounces around 14.7 on my wideband. Below, 1200 it pegs lean, idles rough and will idle for about 15 seconds when warm then dies out.

My ISC tested fine, I've adjusted my TPS and throttle cable. Car used to have cruise and has a non cruise cable now. Emmisions are deleted as well as ABS.

I've attempted to adjust my BISS but I can't get the car warm enough/run long enough to perform the procedure so it is at 2 turns from bottomed out with ZERO leaks coming from it or anywhere else for that matter that I can find. I am honestly not sure what exactly you guys need to see for a log either. So just let me know what you want or any information I can give you and I will supply it! It's been nearly 3 years since I've driven this thing, getting close haha.
