Hbro111 - just for posterity can you post that part# ? I searched 4-5 different phrases without finding it, even by including johnhef's sig. Adding the part# here should make it pop-up better in the future.

Parts list for Idle Air Supply lines 420/560 engines
I put together this list after responding to several threads for "lumpy idle". If you have never had these items replaced, they are 18+ years old by now and probably brittle. A potential source of vacuum leaks too. An easy DIY to replace in an hour or so. If you go further and replace the injector seals and holders (also recommended if they are original), add another hour plus. Replacing the injectors at the same time adds no more time, but it does add to the cost. Attached list is from AutohausAZ (I wanted to credit their format).
Best-
Dave
