    bogging down - popping

    Now that the engine is broke-in.

    A quick stab of throttle it's bogging down popping. Like a carb with bad accelerator pump.

    moderate throttle up it's fine

    edit, Turning down fuel pressure, had it at 58 - 60 with vacuum, so that must of pushed pressure over 70 with quick vacuum loss. Checking later when I take car out.


    Other thing is I'm not going into PE consistently, even when throttle voltage is met.
