I'm having an idle issue whenever going in and out of gear. When going in gear the engine will idle. When going out of gear it won't cleanly pick up idle speed. If you just lightly blip throttle it cleans up.It's 4150 ,950 [830], IAB 70,MAB 28, IFR 31 lower, mix screws 1.5 out [ yes I'm on the idle circuit] mix screws are responsive. Fuel pressure 5lbs holley blue pump. Floats halfway up sight glass. Idle timing 25, 34 total. 446 Indy EZ heads, Mopar 590 cam, TorkerII intake with 2in tapered spacer. 8 in convertor 5200 stall. Idle speed is 12-1300. drops to 800 in gear. 8in vacuum at idle. MSD pro billet dist,6 AL box. What is blipping the throttle telling me?
