That strongly implies that the plug or plugs are not firing at all.
bad fuel bad spark plugs incorrect timing
Dirty fuel injectors or spark plugs
Wet/damp/faulty ignition wires, contaminated fuel (water), worn out spark plugs.
My best guess would be the plugs aren't igniting the fuel and it's collecting on the plug.
No, spark plugs do not cause ignition in diesels. The fuel compression causes ignition
Check for spark at the plugs. Check for fuel to the engine.
Replace the spark plugs and wires. Replace the fuel filter.
It could be numerous things. From a bad fuel pump, for bad spark plugs.
Weak fuel pump, partially clogged fuel filter, bad spark plugs or plug wires.
No,car will not run rich.Infact it gives misfires since escaping fuel will be the ultimate result if we use wrong spark plugs.
Yes it can. If the sensor sends a false reading it can cause the pcm to over fuel the engine.
Either lack of fuel or lack of air. Check your fuel filter, fuel line, spark plugs, spark wires, air filter, and air box.
