Idle Issue

[kis86]

Hey guys,

When I start my car, the idle goes wayyy up, then down, then up etc for about 10 seconds. Any time I come to a stop sign or go through an drive-thru etc, it idles very rough and has died a couple time in the laft 4 months.

My thought was spark plugs and/or ignition coil(s), but I'd like to try anything else before spending money on something that might not be the problem. Anyone have an idea? I saw maybe cleaning the throttle body might help...
