Heres the deal. I disconnect the MAP sensor it smokes at idle a whiteish smoke, hunting idle, but runs great at WOT. Plug in the MAP and it skips a beat at WOT between shifts idles at 800 alright.
I disconnect the IAC it dies. Timings been played with from 16-8 i set it back at 14. I just put the exhaust on. and I broke an O2 sensor. so i just filled in the exhaust holes with a plug and left the o2s out. But O2s dont get read until the engine is warmed up. it does this in closed loop mode too.
Now it ran perfect before i deleted the emissions and the a/c and started ripping out vacuum lines. Vacuum Line still goes to the MAP sensor.
Plugs wires all tune up stuff is brand new.
My guess its leaning out at WOT around 3 grand and on it will skip a beat.
But all vacuum lines are plugged? So that shouldnt cause it to run lean if thats even the problem.

removing the EGR will cause a poor idle at initial start up, you need to also disable it electronically.
you really NEED to put the O2 sensors back in the car
until you fix these deficiencies, you cannot begin to troubleshoot any other problems

Disabling emmissions eletronically...how would I go about disabling it?
o2 sensors are being ordered, are they different on a9L cars because im going to be swapping for mass air when I do my h/c/i.

you gotta put mass air on speed density with a cam! my first mistake and couldn't figure it out for like a year...haha...i did the mass air conversion and WALLAH!! fixed! no idleing issues! do that and it'll fix everything! I can almost guarantee you!
