Reinstalled some bigger idle air bleeds back into the Holley 4412-2 500cfm 2-barrel on the 3.8, from 0.070" for over the winter, and readjusted the idle mixture screws. This time with 0.078", and still no level road load cruise or light/part throttle acceleration surging or complaints. Crispier and minimal pedal accelerating even nicer than with the 0.076" IABs in it last year and previous when it averaged 32mpg.
