bad misfire only on idle

hey,

only on two occasions now has my jeep done this in the last month but thats two too many. Once its fully warmed up and been idling for a bit if i shut it off, leave if for a few minutes then restart it the thing misfires and runs horrible, sounds like its running on 4 cyls'. as soon as you drive it off it clears itself up and is normal again? anyway experience this, it seems like its loading up on idle and fouling the plugs causing a misfire until it gets moving but i dunno, coolant temp sensor maybe?

mine did that for awhile...I did a COMPLETE tune up on it, and BAM !!....all gone.

New parts (tune-up) may help but beware the injector connectors corrode and may behave exactly like an ignition miss. Especially if it's been wet and usually at idle for me. Engine is shaking the most at idle and defeats a marginal injector connection.

May or may not be your trouble but it's something that's happened to me.
