<IMG src=smileys/smiley18.gif border="0"> I need help finding a reason why my new 99" dodge 2500 4x4 has started to have dry start after sitting a few hours and started making knocking sounds between shifts. It was the perfect truck until it started making bad noises. Iwould like it last many years in stead of many months. I tried locus oil treatment but didn't work. Please notify me if any one hasan idea.
