1997 Chevrolet Astro 4.3L Hesitation, Misfire, Poor Fuel Economy, MIL Lamp on
Scope checked crank sensor and ignition module, both ok. Checked cat back pressure and its good. Fuel pressure is right on. Seems to be worse in damp weather but I cant find anything when spraying with water. What am I missing ?
