    My justa idles around low 700's to high 600's. I have noticed in the last few days that at idle there are times when it sounds steady and other times when it is rough and almost sounds like it is missing a little. This can happen in the course of one drive with several stops. Any thoughts?

    Adjusting to the temp changes as fall approaches possibly.

    A/C on or off?

    How many miles and have you looked the spark plugs?

    The temps have been swinging a bit lately come to think of it. A/C is off and she has almost 34K. I have been caught in some constructions sites lately where I had to idle longer then I wantd to. Fouled plugs did come to mind. How often should you actually change the plugs?

    edit: Never mind. Found the thread that addresses this.

    This might all be in my head, but I have made a couple of mods, changed my driving habits and I believe we just went to winter gas here. So, I disconnected the battery and flashed (rebooted so to speak) the ECU. Things seem to be much better. I did this once before and thought it helped then too. Is there anything to this or merely my seat dyno??

    Try Techroline

    Just a suggestion. Try putting a bottle of Chevron Techrolean in you fuel tank at your next fill up. Comes in a black bottle and available at most auto parts stores. It will straighten out your fuel system and usually cures a rough idle. I do a bottle at every oil change. Works great, its worth a try.
