I would doubt that your IMRC is bad. I will be willing to bet that it is your LIM (lower intake manifold). It gets really gunked and dirty. The Secondary Butterflies are in the LIM, just below the UIM (Upper Intake Manifold). What you both need to do is clean the hell out of the LIM. I had the same issue(as did a good have of the board at one time or another) and after the cleaning it is fine. Don't blow your $130 when all you have to do is buy some new gaskets ($20) and a can of TB Cleaner ($5). The kicker is that it takes about 5 hours the first time that you tear it apart. Take a weekend afternoon and get to know your car! Check the "How To" forums and you can get very helpful instructions.
