    Hi all… recently my idle became rough, it shakes the truck a little at stop lights (2003 2.4L). I removed and cleaned the throttle body, it was dirty but not atrocious… the engine instantly ran better. This only lasted a day, though, now the rough idle is back. I looked into the throttle body, it's not gunked up again… any ideas what's going on? Thanks.
