Throttle blade question
I just bought a 01 2500 with a 6.0. It idles low when I come to a stop for a few seconds before it can "catch up". I'm thinking clean the throttle body, so I looked at it to see how dirty it was. When I pulled the intake boot off the hole in the throttle body has a yellow rubber plug filling the hole. Everyone I've seen has just the hole. Has anyone ever run into this?

I'd try removing the rubber plug which should actually raise the idle a tad. Before tuning became common and readily available, guys used to compensate idle issues with larger cams by drilling out a hole in the throttle blade. (Definitely clean the throttle body also though)

Make sure you remove it to clean it. I cleaned the front of mine and it looked good but when I reached in with my finger it was nasty. I removed it and cleaned the whole thing and it totally got rid of all my idle issues.
