theres a guy around the corner from me who i was talking to, he has a pipercross panel filter in his so we swapped and went for a drive and the problem was solved.
it started instantly without haveing to press the accelerator ticked over smoothly and power was also smooth and progressive.
put the old panel filter back in last night and this morning pig to start again so off to get a new filter in a mo when ive finished at work dont know what to do for best now though panel or induction?
