You may have too much gap if it's missing at high RPM or load. Did you check
and make sure all the wires are well connected?

        Subject: DML: Misfires -- Need Help

        I installed the Bosch Platinum +4's this past Monday and I noticed
what I
        think were several misfires at high speed -- about 65-75 MPH. It
happened
        going up a very slight grade with about 1/2 to 3/4 throttle (auto
tranny
        did not downshift or come out of O/D) and does not seem to happen at
WOT...

        My truck is a '98 318 with ~10k miles on it so I don't think it's
the coil,
        distributor, fuel injectors or other stuff that can cause this. I
did put
        my FABM 10" back on at the same time I put in the new plugs and I
did reset
        the computer...

        Is it possible/probable that the computer just needs more time to
adjust
        and I should just wait this out or should I just go ahead and start
yanking
        the plugs and check gaps (even though they were "factory preset")???
Is
        there a better way to diagnose the cause of a misfire?

        Thanks in advance for any help.

        T.

        P.S. I wrote to Dave (Fish) who also recently installed these plugs
and he
        does not have the same symptom/problem... Thanks for checking for
me Dave!
