6.4L erratic idle when super cold.
Hey guys, I'm having a problem with my 08' SD 350. when it is super cold -25 or colder or when it is -15 or colder and it is not plugged in the idle hunts. When I fire it up it the idle drops rapidly and then just like someone stomped on the gas for a second it aggressively revs up to 1500 RPM...- sylvanlaker
