I HAVE A 89 S-10. IT HAS A 4 CYL. 2.5. IT RUNS REALLY ROUGH AND BLOWS BLACK SMOKE OUT OF THE EXAUAST. IT ALMOST FEELS LIKE IT IS GETTING TO MUCH FUEL. WHEN I GIVE IT GAS IT IS REAL BOGGY AND WANTS TO STALL. I CHANGED THE OIL, AIR FILTER, BREATHER, FUEL FILTER, PCV VALVE, MAP SENSOR, CAP, ROTOR, PLUGS, AND WIRES. IT STILL RUNS BADLY. THE CHECK ENGINE LIGHT ISNT COMING ON. I WAS TOLD IT COULD BE THE IGNITION MODULE. I WILL HAVE IT TESTED TODAY. ANY SUGGESTIONS OTHER THAN THE IGNITION MODULE?
