Really low idle, not sputtering or dying?

Hey guys , I have a 96 GC Limited with the 5.2 in it, and when I start it up, it starts perfect, but once I start going, whenever I stop at a stop sign or a light, it idles at like maybe 300-400 rpms? the very first line on the tachometer above zero. It NEVER dies, NEVER sputters, idles just perfect. Is this something I should be worried about?

Try cleaning your idle air controller (IAC) and throttlebody. Mine Idles perfectly now.

^ I agree. Usually a low idle problem is a case of a dirty TB.

^ Agreed. Since you're seafoaming, might as well put some in the crankcase and change your oil afterwards. I use an aerosol bottle on the throttlebody for ease.

FYI You need a T-20 (Torx bit #20) socket to remove your IAC.
Hope it solves your problem so you can move on to the next of hundreds.

Mine idles really low to, in park at around 500, and stopped in drive around 200-300. I need to do a tune up soon, never cleaned my IAC but have seafoamed through the brake hose line. Maybe I'll seafoam again just everywhere
