Hey guys, I'm new to this forum so I hope I'm posting this in the right section, my 96 ram 1500 5.9 has been squeaking lately, I figured it was coming from one of the pulleys. Today the truck stopped squeaking, but developed a bad vibration when it's idling, vibration seems to calm down when I hit the gas but immediately starts again when I take my foot off the gas. Any ideas why this is happening would be helpful it's pretty annoying.
