Default Rough Idle

My wife's 05 Mustang GT(Auto) crapped out on her with the "Evil Wrench" indicator, all codes pointed to the throttle body (62mm BBK)
I cleaned it, replaced the TPS, replaced the TB Motor, new front bank O2's and MAF.
No codes, but it still idling poorly and stalls out at high RPM.
I'm stumped, any one out there experience this or have any suggestions,I would sure be glad to hear.

Do you possibly have the stock throttle body to replace the BBK and see if it still has the same issue? How long was the BBK unit on the car (miles/time)?

Generally those Throttle Bodies are junk. Replace with stock then check
