I have a 3.1 v6, I replaced the sparkplugs, cleaned the throttle body, replaced the IAC valve, checked for vaccum leaks, and STILL whenever I come to a stop in any gear the rpm will dwindle down and then it will cut out/die, it will start up no problem after that, but the problem will not go away. When this happens, the engine light comes on, im going to get that checked out but does anyone have any idea what this could be? Im stumped.
