I was driving to cincy when my car started losing power. I had no throttle response, could barely make it up hills, and the car would sputter under heavy throttle. No check engine light came on and none flashed would I grounded the connector. I've checked the following:
TPS (in range)
AFM (all values in spec)
Fuel Pressure (stayed around 35-40psi)
Spark on all plugs
I checked for vacuum leaks and found none
I even created a gasket "block off plate" for the acv to make sure it wasnt leaking

Now when i give it any gas or WOT i can't get it to go above 2000rpms. I've attached a video for helping diagnose this. Cost me $500 to tow back home so I'm pissed and ready to blow it up. The only thought I have now is either throttle body or clogged cat. Honestly I have no idea though. Thanks for the help.

If the key were to on and the flapper to the AFM were opened manually by hand is there voltage on the Blue wire at the Circuit Opening relay? There should be.
