Bad TPS?

Having some throttle response issues. Issue is there is zero throttle response. Linkage is all intact and the throttle plates inside the throttle body are moving, yet there is zero response. Engine idles fine and there are no problems starting. Recently changed over to an Accufab throttle body, but everything has been fine until now. Any thoughts?
 
Check to make sure that the following connections have been made;

1. MAF connector is connected
2. IAC connector is connected
3. TPS connector is connected

Un-plug and re-plug each of these.

If all looks fine then I would remove the TPS from the Accufab and make sure it was installed correctly.

Let us know what you find.
 
I don't think it to be a bad install since car was running fine prior. Just going to buy new TPS and see if that does it.
 
Check the TPS install on the Accufab TB; If NOT installed Correct, No throttle response!!! It should have a slight spring load (TENCITON), if installed correct.
 
Strange if there is no code thrown. If you have a code reader check it out for the hell of it. If you have the chance try disconnecting the battery overnight, probably wouldn't hurt either.
 
Tried both, leaning towards a mechanical issue in the throttle body. Checked and re-checked TPS, ruled that out.
 
Figured it out. Screw on the shaft that runs across and through the blades was just loose enough. Wouldn't slip when manually fluctuating the throttle by hand, but would when pushing the pedal. Thanks all for the suggestions and input!
