Need Help Diagnosing Problem
I had lent my car to a friend after leaving town for two days to go buy some HID's for my car, and when I came back i found out that my Gti-R was not what it used to be. Other then finding out that my friend put over 300km's on my car in under 2 days, I noticed that my car would loose power when ever i bring it over 3k RPM, or whenever i go up a hill, it also keeps slowly reving up too.
When i really try to give it some gas, it would rev up to about 3k then just climb up to 7k RPM and go no where for a bit then drop back down to 5k before going anywhere.
I would like to know what you guys think about this problem, my best guess is probably the clutch has gone, but i would like to know what you guys think.
