What causes the spark plug wire to wear?
What causes the spark plug wire to wear?
This wear can be caused by engine vibration, contact of the wire with the hot engine, friction or abrasion and even corrosion from exposure to certain automotive fluids such as battery acid. Electro-Magnetic Interference (EMI) is a problem created when spark plug wires are not properly shielded by carbon suppression conductors.
Why are my spark plugs wet with gas?
Fuel fouled spark plug Black fluffy carbon deposits indicate an overly rich fuel mixture or possibly a weak spark. Check for such things as a stuck choke, a heavy or misadjusted carburetor float, a leaky needle valve in the carburetor, leaky injectors, low coil output or high resistance in the plug wires.
Can a bad spark plug cause an engine to missfire?
If the engine starts to buck, stumble or missfire you could have a ignition related problem like a spark plug wire or ignition coil. if the engine bogs down and looses power you probably have a lack of fuel pressure or fuel volume problem with the fuel pump.
Why does the spark plug arc when the engine is idle?
This is due to the throttle being almost closed, the engine rpm being low, and the fact that there is no load on the engine. If the engine was still idled and a load was gently applied (engaging a PTO, for example), the voltage required to arc the plug would increase dramatically.
Why is my spark plug not working in my car?
It depends on what specific trouble code is being stored. If it’s a specific cylinder it could be the spark plug wire (if your car has them) or a bad fuel injector (if you have individual injectors for each cylinder). It could also be low compression in that cylinder. If it’s the generic P0300 misfire code, that opens up more possibilities.

What kind of spark plugs do you use?
Plug leads are usually carbon cored. They look alright from the outside, but inside the sheathing there are gaps in the carbon string which occurs over time and breaks down. The first thing I did when working on a Ford was to sling the plug leads and fit copper cored leads.
What does P0300 mean on a spark plug?
Many times, P0300 occurs when there are worn out spark plugs, spark plug wires, or a faulty ignition coil. P0300 should be repaired immediately.
