Lannyx,
Does the traction control light flash when your car "brakes itself"?
If not and it just loses power, like driving a 4 cylinder car then you need to replace your IC pump. There are some great "how to" articles on here. Very simple to do.
You are running premium (super unleaded) fuel 93 octane or higher in it, correct? You are not getting a "check engine" light either, correct?
