Help with my new (high mileage) GTO
I am a new GTO owner and had a few Qs.
First off, the car is a 2005 GTO with 87k mi midnight blue.
I received the car with an unknown service history so the first things I did was oil change, air filter cleaning (got it with a k&n) spark plugs, rear diff oil change and both belts changed. Now the question is, what needs to be done to this high mileage car to bring it back to optimal stock performance. A guy i work with has a stock 2006 with 50kmi and he agrees that his has a bit more nut.
I want to make this a project car (after a while of getting used to having significantly more power under my foot) but i want to make sure it runs perfect stock before I start modifying it.
