whoa, whoa, whoa......the car had to be towed home, you had no idea what could be wrong with it, someone checked it out without making any replacements, and you took it for a test drive?? You are damn lucky it wasnt something major, because then you'd be making a new thread about how your car is dead.

just a fyi.....anytime you have to tow a car home from a problem, it's probably not the best idea to take it for a test spin and "get on it".....sheesh.
