how's your MAF? Unplug to see if it makes a difference
has are your spark plugs and wires?
are there any mods done to your engine? Could be a tuning issue
Hopefully some geniuses on this website can help you out!
Yep a few mods done to my LQ4. I have a Tick Performance cam (222/234 .610/.595 113 lsa, Dual .660" spring kit), an SLP polished intake, Nick Williams 102mm DBW polished throttle body, stock bottom end, T-link for the DBW setup and throttle body, brand new Accel 9000 ceramic boot wires, brand new plugs, brand new fuel injectors in all 8 cylinders, VATS is turned off in the tune and we have it setup to default to speed density if the MAF isn't working but i'm not getting ANY codes on from the computer.... It's pissing me off. I made a long post just above yours in this forum hoping that the LS gods can help! lol
