Its not the valve. It is going to be a plugged up port. Common problem on the 98-02 V6. There is a TSB with the procedure. Just google 99-085 TSB. The first hit shows the procedure.
I recently helped my friend with this. It really isn't too bad to do. The throttle body gasket stuck to the intake, so we had to scrape that off. We replaced that gasket. I skipped steps 8-13. Just used the drill bit by hand to clean out the passage, then a test tube cleaner + throttle body cleaner to remove the rest of the buildup stuck on there. We also replaced the gasket between the cylinder head and the intake manifold just to be safe.
