Hi,for my opinion,

  • check fuel quality (suffecient fuel supply)
  • fuel contamination (dirt,water)
  • fuel line distorted
  • engine support defective
  • air leak
  • lastly, you may perform compression test

Check engine light on engine acts as if missing new plugs wires and #5 spark pack missing again 6cyl 4x4 3.4 185000 miles


was it running this way before you changed the plugs? just a shot in the dark here possibly a defective spark plug, rare but not impossible. if it was running fine before changing them. Other wise I would take it to autozone and pull codes if it is P0350 #5 misfire we would use the process fuel, fire and compression. is there any engine coolant around any cylinders? Have you checked the coil packs? could be a bad coil pack. if no evidence of fluid around them proceeded to check for spark, fuel then compression. post back results or new post with more deductions. iis it no spark no fuel or bad compression.

ROUGH IDLE 06/E350 MERCEDES - WANT TO TEST COIL PACKS AND CHANGE SPARK PLUGS


If it has not set a check engine light it likely is not a misfire, these models wear out the engine and trans mounts by about 80,000 miles. if it is misfire you will need to read the fault codes and go from there.

97 chevy blazer rough idling problem? help?


It is hardly ever the spark plug or only the spark plug - generally for some reason there is a weak or lost spark and the reason must be found and rectified by carefully checking and then replacing any components found to be edfective - plug wires, coil, distributor cap, rotor (if fitted), wiring, connections and could conceivably even be the ECU. Perhaps the misfire is due to injector trouble...

Sometimes a fault with persist even after it has been "cured" until the fault code is erased with diagnostic equipment.
