hi , please can anyone enlighten me with the problem i have regarding my 2litre club dti on an 02 plate. The problem im having is after about 3 miles of starting my journey i loose power, the rev needle drops to 0 and when i stop the car revs up and down on its own accord,andtheres no pull away power. sometimes the power will kick back in to normal, i have been told this may cost up to £1100 to sort the problem, but i have been also told that the problem may be a sensor. i will be greatfull for any advice.

it sounds as if you have a problem with the crank sensor or even the mass air flow sensor,my advise would be to take it to a vauxhall specialist and get them to check the management system with tech 2 to see if any fault codes are stored.they also have a throttle cut off valve that have been know to stick and this can cause the car to loose power.
i hope this helps

i would just like to thank Craig-michael for his advice, i took it to vauxhall and it was the crank shaft sensor, so now the car is all good , thanks once again Craig for your advice
