Manifold Heat control Valve

Mine appears to be pretty well stuck in one position, and I fear that is the closed position.

Short of disassembling the entire manifold and sawing this thing out, how do I fix this?

I have tried vise grips, hammering, liquid wrench. It will not budge.

I fear that this is affecting my gas mileage and performance, be that as it may.
