SHe did answer several posts back, Dave. I'm wondering about this "SC pulley worked on".... odd.

Anyway, some of your symptoms sound like Tricia's Limited in Oakwood GA. She struggled with it, problem would come and go. Replaced the MAF twice. Found a crack in the intake box (which you don't have) - replaced intake box. Still not right, then in two weeks, it got way worse - she could not even drive it.

Just saturday, one of us here took the throttle body off and, leaving it plugged in, had her turn the key on - the throttle plate started doing a dance. Replaced the throttle body (one of us had a used spare). Problem solved and Tricia loves her car again.

But, her car has 180,000 on it. It is, I THINK the first throttle body issue I've heard of NOT COUNTING those who have done upgrades, of course. Oh, and her car threw NO codes.

(As you have been told, the P0410 code is nothing more than a distraction and emissions thing, it does NOT cause the car to run poorly.)
