My 1994 suburban with a 454 randomly shuts down.

Asked by mquick Nov 20, 2014 at 04:32 PM about the 1994 Chevrolet Suburban K2500 4WD

Question type: Maintenance & Repair

It runs out fine its only seems to be when its at an idle or slowing for a stop. If I drive with two feet I can keep it running. Doesn't sputter just shuts off
