Ok my car was spuddering and all this BS so i took it to the dealership from cutting out ect ect. So anyway i just got a call from the ford dealership for my 2000 ford mustang GT and they are charging me 520 dollars. They said the problem was a dirty MAF, throttle body, fuel filter needs replacing, and fuel injectors. I got the price worked out with autozone and i can afford the parts myself. Only thing i want to know is how hard is it to do all that?
