My Car has a bad stuttering

[Anonymous]

Hey,

Any suggestions why this stuttering could be. Anytime the car reaches about 4,500 rpm, it starts to stutter when my foot is flat. I think its the fuel filter, any other suggestions of what it could be?

If you think it's the fuel filter, change it. It's cheap and easy enough.
If that doesn't cure it, then maybe look at the ignition side (plug gaps/leads etc) make sure your hoses are all tight as boost leaks cause similar problems (but you can quite often hear then) the AFM can also cause problems so it may be worth checking it out.
