    Once again, Ed was right...it’s was something simple.

    Kudos to Ed and Mark for their expertise in resolving this.

    I’m very happy for Arne, but in a way I’m sad to see this entertaining thread come to an end.

    Just think, Mark and I and all the other professional mechanics get to do this stuff every day Ya just gotta step back, stop over thinking, and get back to basics. Glad you got it Arne, that's the best part of this job, when it all comes together!

    Superb help from the Old Sweats here. Reminds me of the sub heading of Agatha Christie’s book with Hercule Poirot “ The ABC Murders. if after you’ve eliminated everything that’s impossible , then whatever’s left , no matter how impossible must be the possible.”

    Hope this is your issue, as it is a really easy fix!

    Just got back from a half-hour drive over the back roads and hills south of here. Car runs great. Will do the final tuning with AFR and call it done.

    A final note. Mark's bench settings for the MFI pump were extremely close. Both part load and idle were borderline lean, so I went 1 click richer on the main rack (part load), and that took care of both. Not planning to mess with this stuff again.
