RE: which cylinders does pre cat o2 run?
well the only thing i could think of would be that i use a 3" maf housing from a vr6 and my pre cat o2 may be bad. the only other thing is that i put a filter on the pipe that comes off the valve cover that goes into the air intake system. now what do think my problem may be? thanks alot for the replies

I think you just answered your question. You may have a leak within the pipe that goes into the air intake. I am not an expert, but it was just my guess that your problem lies within the stuff that you changed.

well i plugged off the hole on the intake and put a breather filter on it just like the lltek kit and other cai kits use. i wouldnt think this would do anything but i just switched back my maf housing to stock bc since i put a larger one on the computer is seeing less cfm so it will lean out the car. i figured i could fix that by putting larger injectors and a adjustable fpr
