Can anyone help on this one--My engine sems to misfire occasionally at just over 6k revs but then works fine over 6.5k rpm-it doesnt do this all the time-just now and again.Could it be the coil pack,spark plugs,earthing ect--btw---is a UK 98 dawes(set at a smidge over 1bar) and scorpion back box.
Is there any common causes of this????

Thanks

I would recommend a new fuel pump
And fairly quickly

I'm sure Arron may be correct but to be on the safe side I would get it straight to a dealer or specialist to diagnose properly if you ain't too sure yourself.....

If you think I'm being overcautious then my 'slight hesitation and/or miss' turned into a bill for £3,567.85 last week

Good luck

Check the spark plugs, gap to .7mm. If they look iffy, replace with NGKPFR7B's.
