journeyforce said:I also had a 1992 S15 GMC Jimmy(the sister to the S-10 Blazer) I was getting 23 mpg on mine(it had the 4.3 TBI motor) Is yours the one that says VORTEC on the plenum or the one with the top of the engine air cleaner? If it is the Vortec one you should be getting 18-20 mpg just driving it. Did you check to see if the "spider" fuel injector was leaking into the plenum? (It was called a spider because it was a big assed fuel injector connected to 6 hoses each attached to a cylinder to pump fuel into that cylinder) the hoses leak and cause fuel MPG and/or running issues. The easiest way to check to see if this is your issue is to remove the cover that says VORTEC and shine a light down and look. If any of the area is clean or has a goldish tint then the thing ruptured and the gas cleaned the area
Good luck
