Thermoquad question

More than a second for sure. Go for a short drive and all looks good, then all of a sudden the A/F #s read very lean for the rest of the way back. But I don’t notice a difference in how it runs.
I’ll do some close inspection of the external parts.

...it seems to be true that the numbers are consistent and normal at WOT. But I’d think the same would be true at cruise and part throttle if it was how much the the butterflies were open.

When I blip the throttle and watch the the rods they seem to operate properly.
