Thanks jim, I'd not considered valve clearances so I will definitely bear that in mind. You reckon the coils are good then?

Drivability issues? Misfire present? Hahahahaha you've not drove one of these things before then yeah? They're bloody awfull!!!!! Seriously tho, there is a miss yes, Mrs says its drives ok but I haven't tried it myself so wouldn't guarantee it! I will check the various other possibilities tomorrow, am interested to check a few other of the 5v feeds too to see what they're like!

Thanks again buddy!
