LTFT problem on 1996 ws6 Hello everyone. I've had this 1996 ws6 Trans am since 2002. It's been sitting for at least 6 years. It has an lt4 hotcam kit, pacesetter Headers, high flow MagnaFlow cats, electric water pump. Lt4 knock sensor, ported and de-screened maf.
I'm using the app torque for these readings. At idle my LTFT on bank 2 are pegged at 25%. When I drive they seem to go down, but at idle they go back. I did some research and it seems it may be a vacuum leak so I changed all suspected hoses. We also cleaned the fuel injector system using the otc fuel injector system. Ran a little better but torque shows that LTFT on bank 2 are high.
Where do I start?

I would start with the basics. Are there any exhaust leaks of any kind, swap o2's and see if the other side does the same thing. Make sure you dont have any burnt plug wires.
