This is a stock TB that has been bored out to 54MM. Every once and a while, after startup, if I rev it, it won't came back down all the way to regular idle. I'll have to pop the hood and push it to the stop screw to get it back to regular rpms. It has also done this while driving. I lubed up the cables with liquid graphite, still no change, what else can I do?

Thanks guys, I'll try that tomorrow morning and post up whether it worked or not, of course I'll have to wait til a week or 2 of driving to see if it shows up, it doesn't happen everyday, but it has happened a lot recently.

my bbk did the same and come to find out the actuator on the damn thing had sepporated and I had to tack weld it to keep it in sync ,should have contacted bbk but did not want to send it back and waite.When i took it off to weld it took it apart to clean it and found to large flash (casting ball) knots in the IAC valve area glad those little ***** never made it out
