Just replaced opti, plugs, wires, got rid of all the emiss crap and tuned it all out with TC.. Also tuned out the MAF to rule that out as the issue. I see very low o2 readings on the L bank. Seems like it gets heat soaked and runs like garbage.. on the freeway it runs great and has loads of power.. If you rev in N it will hunt for the idle when you let off (RPM will drop and then try to find 800)..

this is a log of idle with a couple revs with maf tuned out

and this is one of me driving last night with the MAF still there
