Running Rich P01075 Hey guys, I have a 99 Z28, and I keep getting SES light for running rich on bank 1 and bank 2 both sensor 1's. I checked my short term and long term fuel trim, they both seemed fine, and the o2's are reading correctly when I hooked it up on the tech 2 at work. Has anyone ever ran into this? I have no headers or anythng, only a cat back and an air filter. Air filter is clean, and the mass air flow is clean, no oil on it from the air filter or anything. Any help would be appreciated.
