Hi,
My Astra has developed a stutter at around 2500 rpm when travelling at a constant speed and when you are just feathering the throttle, it acts almost like running on kangaroo juice also the engine warning lights comes on when the tank is running low. If i use a higher octane fuel the problem is less pronounced. I am thinking fuel filter or fuel pump ? Any advice would be apreciated
Thanks

the filter is located on the pump assembly .. it could be the filter or pump or a clogged/bad injector .. you could try adding a good fuel system cleaner to the tank to clean the sytem and injectors before replacing part's !! hope this helps
