Have a look at the TB inside, if it has any buildup around the throttle blade idle setting. Clean it with like acetone on a clean towel, you can get pretty much most of it without removing the TB, that could help and cost nothing. May even help engine starting. Dirty IAC too or 'idle air control' valve.........but they suck getting to on these.

If car doesn't do it in normal driving around town, I'd tune it out of my head.
