Need Help ASAP
Ok so I did some work to my car saturday night, I put in a 3rd gen alternator, all new belts, and i removed my airpump and put a blocking plate in instead (with gasket) now when i start my car the idle is horribly rough the car runs super rich and also it creates 0 boost, I have a Apex I Power fc and i am running off a map sensor only, does anyone have any suggestions on what could be causing my problem, I need any help I can get the car is my only way to get around. The car ran 100% before I did this work, I dont know what I may have done wrong.

I'm curious, How do you know you're running super rich? Wideband O2? I wonder if the FD alt. raises the ref voltage on any of the sensors. Could that possibly throw the ecu off that way just from the increase in voltage/current by the FD alt?

i have a wide band O2 and its reading 10.2 at idle, it used to be 14.3 at idle and the car will go through the entire rev rang finwe with out load but as soon as any load is put to it the lack of boost it just boggs itself out because it so rich, my question is should I have to do that much of a retune after removing the air pump and avc. So everyone knows its a 89 S5 turbo.
Oh yeah I cant find a vacuum leak any where around where I did any work, I have looked all over but mostly just at what I changed, (does any one know what should be done with the 3 metal lines that went in to the avc, I just plugged them off thats what I though is suppose to be done.

the blocking plate covers where the avc was, i used a new gasket and its a simple plate with 3 holes for the studs to go through. and thanx I love the power FC, it works great, but right now I am wondering if maybe the fact that it does not self adjust for anything, is causing my issue.
