    OK, thanks, I'll have a look at the timing marks.

    Could an incorrect cam position on bank 2 be causing the hesitation symptom and/or could it be related to the lean condition on the opposite bank? ...or am I looking at two separate issues? I expect that the bank 1/bank 2 problems are unrelated, but then again I'm rarely accused of being an Einstein.

    It might be related and it might not.

    Cam duration/lift/timing, do effect vacuum in the intake, and could very well upset the mixture if not in sync.

    The cam sprockets were indeed out of alignment. They were tight to the shafts so I don't think they slipped. According to receipts, the timing service was done by an independent repair facility; perhaps they did not use alignment tools.

    Measurements are much better but not exact... I don't know what went wrong there, as I used the alignment bar and the crankshaft lock:

    The fuel trim readings have improved as well:

    However, the tip-in hesitation/lurch issue remains in all it's glory... no improvement is evident.

    I noticed that the ignition timing bounces around quite a bit at idle, with an approximate range of 6 to 17 degrees BTDC. Is that a concern or is it normal?

    Mike

    P.S. I checked the brake booster and associate plumbing per previous advice... it is is great shape.
