1989 gmc s15 pickup gives only 12 miles per gallon
We recently bought this 1989 gmc s15 which has 112000 miles.
Changed spark plugs, changed tires after bought it...added fuel cleaner and heet for possible water in fuel line...
what brand of spark plug wires,distributor cap/rotor and air filter we should buy?
what else we should do to improve the fuel economy...I checked it should give approx. 20 but this one gives only 12...
its looks like on low rpm (when we run from idle to up to 10 mph) its has low power...
what is the solution?
