Doing some datalogging today and I noticed that sometimes while cruising down the road the trims go to "0" and quit responding. The a/f will start moving around a bit at this time since there's no O2 compensation. Then they'll go back after a bit. They might stay off for a minute or more, and it's not when the engine is cold or sitting idling. Are they somehow cooling off or is there something set in my tune incorrectly? I cannot find any correlation on my logs as to why they shut off, or why they go back on.
05 GTO LS2 with twin turbos.
