Out of nowhere engine began to idle erratically almost causing an accident at an intersection, if I hadn't caught it and slammed on the brakes the truck would have rear ended another vehicle. After that the idle began to drop as if the vehicle was going to stall, then would kick back up to about 900-1000 rpm. Was intermittent at first, now vehicle is not driveable. It is worse with a/c on and it effects engine temp gauge as well.
