I'm Awesome
Hey foks - 1998 K2500 5.7L pickup with 248000 miles. Had it in the shop for some misfiring that was going on, and they said it needs a new intake manifold gasket, which I have and am planning to put in. It had been running smoothly up until a few minutes ago when I noticed a sudden vibration at idle, strong enough to be noticeable while sitting in the cab. I got it home, popped the hood, and went to restart it again, and it started reluctantly, but then ran ok once started. Would you think that fouled plugs could cause a vibration like that? Thanks-
