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.
Yes, a clogged catalytic converter can lead to fouled spark plugs. When the converter is obstructed, it can cause increased exhaust backpressure, leading to incomplete combustion and unburned fuel entering the exhaust system. This excess fuel can then accumulate on the spark plugs, resulting in fouling, which can affect engine performance and efficiency.
It could be numerous things. From a bad fuel pump, for bad spark plugs.
No,car will not run rich.Infact it gives misfires since escaping fuel will be the ultimate result if we use wrong spark plugs.
Weak fuel pump, partially clogged fuel filter, bad spark plugs or plug wires.
Yes it can. If the sensor sends a false reading it can cause the pcm to over fuel the engine.
