Default Need help diagnosing problem (video)
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.
