    Super lean to super rich idle?

    My 05 Vette with cam and heads goes from +20 to -20 within minutes just idling at 190 degrees????

    I can't get the trims to zero out. Any ideas?

    I checked that. They both are correct and both read the same trims.

    Open loop my afr's are 14.4 at idle. Closed loop it demands -20 on the trims. Wierd.
