My car had suffered from the "rough idling, very poor fuel consumption, and the dreaded Drivetrain Malfunction'. Since the repairs which I listed in another thread here, my car feels much stronger, smoother, and better mpg.
The problem now is that folks that are just now going in for this, dealers are very backlogged and wait times are atrocious! I have read from 2 - 10 weeks.
