While doing the emissions inspection on my '76 (2.0 GC) I noticed the mixture was very rich, fluctuating between 3.5-4% CO at idle, I believe it should be about 2.5%. Which way do I turn the ECU knob to lean it out? I thought it was counterclockwise - but it's already as far as it can go... (unless I am wrong and the CO is actually OK, which I doubt) (IMG:style_emoticons/default/huh.gif)

If the TPS is misadjusted, it may stumble right at the transition from idle to acceleration. The only reason I suggested that, was at idle two contacts in the TPS tell the ECU to control idle mixture through an idle circuit and off idle other circuits in the ECU control mixture.
