Went on vacation for a couple weeks, came back, started my jeep, and its had an irregular idle. It doesnt seem to want to die, it fluctuates up rather than dropping down. I let it idle for 15 mins or so and never died. Then drove it around and it ran fine. Any ideas what to check?

For sure we need more info on engine, year. stuff like that. But, if its fuel injected i would say throttle position sensor.

oh yea, guess that info would help. its a 91, 4cyl, and it is fuel injected. so I guess ill start with that then. thanks bud.
