Just changed my 1998 B5 TDI (189k miles) sport saloon for a 05 B5.5 estate 2 lt petrol, can't make my mind if its the change from diesel to petrol but when changing uo a gear under reasonable acceleration (not hard - just normal) the throttle seems to stick for maybe 1/2 second before the revs drop. making sure I have fully released the throttle and fully depresed the clutch, does not happen every time, the car has a full VW service history and only completed 31k. This does not happen if reving the car at a standstill in neutral- has anyone any ideas


Cheers
