i have a 94 sonoma with the vortec 4.3...i love this truck but it seems awefully weak...what i mean by that yes i know its a v6 truck and built for torque but when you floor the truck it shouldnt red line and take 3 miles to hit 60mph.. without so much as a bark from the rear tires...ive been told its a fuel problem, spark, trans, valves, etc. i cant figure it out....the truck is completely stock and only gets about 10mpg if that and cant even pull my 19 foot boat when my lawn mower can...something is deffinately wrong please help...
