For a few days I couldnt figure out why the car, when warm, would run pig rich and idle like crap. Cold startups were great but it seemed that something was wrong when it went into closed loop. So finally today I hooked up my data logger and found that the damn o2 sensors were criss crossed. They were in the wrong banks so each bank was fighting each other. The sensors were dirty too so I just exchanged them on warranty and replaced them. After that she ran great. What a brain fart moment. Lol
