need some help guys Okay guys need some help. I have a 1999 ws6 with a 6.0 iron block. Ls6 heads and intake. A bigger cam. Not sure on specs. Exhaust. Stock injectors. 12 bolt with 3.73 and axles. Etc.
So I started my car one day and it was running like crap and my aide fuel gauge was pinned at 16. First time it has ever did this. Service light came on and scanned it. Came up the rear o2 sensor and fuel injector circuit malfunction. There was no movement in numbers on the rear 02 sensors so I looked I to it and I decided to unplug the wide band o2 to see what happens and it actually ran better and pulled harder. But the idle is a little unnormal. I bought a new wideband o2 sensor and it does the same thing so I unplugged it again and runs better but same thing with idle. Any ideas guys. Thanks.
