Hi new JX owners, I have my JX for a week now and it's now 330km (~200 miles)
Everything runs fine and we're happy so far, except that its idling feels a bit rough and unstable -- at idle, the RPM would fluctuated up and down a bit from time to time. I can feel that rev change in the cabin.
Any of you feel that same?
I'd guess that it could be caused by the still-green engine yet to be broken in... but I'm not sure...

Theres is another thread of this problem, i have about 3000km on my jx and am getting the fluctuated idle.

Any chance the RPM fluctuation coincides with your radiator fan engaging/disengaging?

Not sure. .. why? How to confirm?

it may be because the motor needs to be broken in also there is chance it could be your idle fans when not in motion

How often do the revs change. Pop open your hood and listen to see if the fan in the engine bay turned on when the rev changes.
