Hello there ard. You were exactly who I was hoping to see! Below is my OBD Fusion report in txt that I hope stayed readable.

It is a 2007 x5 3.0si regular gasoline

I cant check for exhaust soot or vac leaks yet. Am I worthy of a smoke test I read about somewhere here? I could post a pic of the original plugs if that would help anything.

It hesitates and has no power all the time . I had no CEL for awhile then it spit the p0420 and 430p and drove fine. About 100 miles after that came the p0300, 301, and 302 codes with the power loss

I only drove this car about 480 miles since buying so most likely the problem started with the previous owner.
