slight shaking when idling
 
hi all! haven't been on in a while, no issues with the Jeep until last week.
out of nowhere it started doing this weird thing when I'm stopped at a light or in traffic idling. (it doesn't do it every time, but almost every time depending on how long im stopped for) I feel a shake or hesitation or shudder similar to the feeling you get when it's going to stall, only not to that extreme. I'm not worried it's going to stall, but it's definitley not right. the engine doesn't make any noises when it does this and the engine otherwise is running totally fine, doesn't sound different. No check engine light and the gauges aren't fluctuating or anything when it does this.

worried it may have something to do withe cylinder misfires....:(
it's a V6
taking it to jeep this week

Finally cleaned my throttle body, and put a whole can of seafoam in my gas tank. The idle seems to be smoother.

Disconnected the battery and used a soft cotton cloth and some alcohol.

Maybe it's the cylinder misfiring or something. But I don't have a check engine light

My '11 had gotten a tad bit of a rough idle. I had to make about a 1000 mile round trip week before last so on the return trip I filled up with 89 octane NO Ethanol. The idle seems to have cleared up.

Just for info, I was getting 22 mpg running 87 octane 10% Ethanol on the tank going and I got 24 mpg running the 89 octane NO Ethanol on the return trip. Speeds around 75 both ways all interstate.

Thanks it's impossible to find gas without ethanol around here.
