Hi IS Community, I read about the 2002 IS300 clutch and ECU Chip. I heard that the clutch wears down or breaks or whatever, really fast. When do you usally notice this (Miles?) and how will you notice it (sound?, working order?)? Do you hear like an odd sound or whatever to know it needs to be fixed? Also another thing, the ECU computer chip. How do you re-program it? I heard that messes up too on 2001-2002 IS300's. Please respond back, thank you IS community.
