Rough Idle

I have an 06 rubicon unlimited and once in a while it will idle weird. Rpms go up to 1000 and you can feel the engine shake like its about to stall but computer keeping it from doing it. A/C on or off same and it does it at radom times. Usually when stopoed at a red light it will do it. Any Idea or just normal.

I had the same issue on mine and it turned out to be the throttle position sensor.

A throttle body cleaning might solve the problem. You can do it yourself or pay $60 at a lube place (like Valvoline instant oil change)
