Hi, I am going nuts. I have a Dax Rush with what I believe to be a fuel problem. It is hunting at idle and misfiring when acellerating. It is driving me mad. When I turn the key a few times to prime the system with fuel it starts ok and runs for a while then does it again after a while.
I have changed fuel filters and pump. The old pump made some funny noises ocassionally and the new one is doing the exact same thing.
Any ideas whats up? It is a Sierra 2.0i engine???? PLEASE PLEASE help.
