Thanks. The generic P0638 is for the throttle actuator. That looks like the winner. I was really hoping for a wheel bearing...$175 and an hour of my time.

I just checked out the DIY and it doesn't look too difficult. I will tackle it myself. My only problem is the generic code reader I have doesn't tell me which bank. I guess I have to buy a BT tool for that unless someone has a suggestion.
