High Idle
I noticed my car idling very rough at 500 rpm yesterday. This morning its idling between 1500 and 2000 rpm. The CEL came on for 5 minutes and went away, will I have codes to pull? Any suggestions? It's a 430 with 77k on it.

Turned out to be an unplugged vacuum hose, driver side near firewall. Easy to spot after removing the air filters.
