i have a 96 s-10 with a 2.2 liter..it all of a sudden lost power while driving..i've changed egr,map,air and fuel filter..engine sounds muffled and lacks power 3rd gear is about as high of gear i can drive in..hard to take off, got to ride the clutch..breaks are not my hold up..the cat is hollow so it aint blocked..plugs look ok..got a strong fuel smell from exhaust...needless to say im not a real big chevy fan...
