waste of time no fault codes stored and tech one does not even check amal valve or knock sensor?????????
so vauxhall technicians could tell me jack squit..........
my local rr guy told me to unbolt the knock sensor and run it up the road and so did chris H42........... so im gona give that a try tonight.........
problem is if it is the knock sensor picking up vibrations, its something bad cos ive taken all the heat shields off, and the alternator belt and the power steering belt and ive got a flexi joint striaght after the down pipe on the exhaust........
fueling is spot on so there fore this leaves gearbox and engine vibration

...........bastard...........
