well after a couple of days messing around with local garage doing endless diagnostics its not the camshaft sensor its the throttle position sensor
at least this is an easy fix and able for a novice like me to fit myself once I had the offending part pointed out to me 10 minutes not to fiddlely and off we go
well lets see wot the old girl throws at me next
so far this cheap runnerbout has needed new clutch,flywheel and this sensor bill so far £350.00 start of the money pit I feel it coming
