Have a couple of problems with Mk4 Astra. The car holds back at about 3 - 4000 rpm in 3rd, 4th and 5th gear. There is no warning lights on dashboard. The car has just had new fuel filter and had a fuel system cleaner completed. Throttle body has been also been cleaned. Still have the same problems.
Ny ideas ? I was told there is pointless plugging the car into computer.
Can anyone help please ?
Many thanks
