Well I have always been interested in the Pro-Products throttle body and thier EFI intake manifolds. But like the rest of you I stayed away becuase i always heard of them getting stuck at WOT. So when I was at SEMA I decided to have a talk with the tech and told him about the problem. Of course they already knew about it and he discovered the fix like most of us. by fixing it him self.
Here is the FIX: The Butterfly has 2 screws in the back. Loosen the screws and smack both sides of the butterfly shaft with a rubber mallet. This should center the shaft and you can then retighten the screws.
I was assuered this was the fix and that the newer models should have that problem because they changed thier manufacturer. I haven't tried it yet but if anybody in here has one and is haveing that sticking problem let us all know.
