Hello, I have a 2000 Jeep Grand Cherokee with about 160,730 miles, and I had a question about rough idle. Within the last few months I have replaced the fuel filter, spark plugs, crankshaft position sensor, air filter, cleaned the throttle body but at idle it is still pretty shaky and not smooth and consistent. My last resort is the IAC Control valve but thought I’d ask for a second opinion before I do anything.

Please provide us with your short-term and long-term fuel trims at idle if you're able to. Or better yet, provide us with a live data sample at idle. That will give us a better idea on what's happening.
Ah, dang I’m not able to do that. But I can say that it shakes a little and sometimes harder than others and when it’s idling, the rpms will be low and then just jump up (not by like a lot) and then go right back down after like 3 seconds.
