check the exhaust manifold and/or gasket for starters. Easy way to find a leak there is to have the engine running, and spray starting fluid all around the gasket area. if it idles down to normal, you need a new gasket.

Yeah, it is..
Take it out, clean it with a toothbrush or something like it. Be careful not to move the pintle back or forth. I would also clean where it goes into your TB before installing.

If you spin it with some pliers (very carefully) you sould be able to unscrew the pintle from the motor, but when i did that to clean it, it worked fine only one month, then i replaced it.
