Chevrolet suburban 1500: I have a 1999 chevy suburban with

Customer Question

I have a 1999 chevy suburban with a 5.7l and it keeps blowing engine one fuse under the hood. All wires show correct resistance even though several sensors are connected to this one small 20amp fuse. check engine light is on and "stumbles" a lot. All grounds seem to be in great shape and no corrosion under fuse box. where do I go from here? help please.
