Yeah. There's an "idle up" feature under advanced functions I believe. It's only meant for when you're running something extra though and you need the power from the alternater for example. It doesnt turn your idle up all the time.

 

Thanks rengnath, my truck just started running rough about a month ago so I think I'll start by cleaning the pcv valve out & go from there.

 

Just try and verify where that vacuum runs to before you pour anything down there. Definetly replace the PCV valve though, they are cheap and its a common problem if it hasnt been done recently.

 

I put the idle from 800 to 860 with my SC. Every once in a while I could feel the idle at a stop, haven't noticed it again since I set it.
