What does it mean when a spark plug is fouled?
Carbon fouling is one of the potential fouling problems that happens to spark plugs. According to NGK Spark Plugs, when the insulator nose of the spark plug is coated, it is considered fouled. The website continues to explain that while carbon fouling can cause problems, if the spark plugs are cleaned,…
Can a car run with carbon fouled spark plugs?
It not only lowers vehicle gas mileage, but it can result in carbon fouling of the spark plugs. Unfortunately, it is impossible to prevent stop-and-go traffic conditions.
Is it bad to clean your spark plugs?
The website continues to explain that while carbon fouling can cause problems, if the spark plugs are cleaned, there should not be any problems afterward unless the spark plugs were also damaged. Stop-and-go traffic, where a vehicle is stopping constantly, is never good for the vehicle.
What to do if your spark plug is fouling?
If one cylinder has oil fouling, a relative compression check can help to assess mechanical issues with that cylinder. Malfunctioning PCV systems are becoming a leading cause of oil fouling in modern engines. These systems have become more than just a spring-loaded check valve.
It not only lowers vehicle gas mileage, but it can result in carbon fouling of the spark plugs. Unfortunately, it is impossible to prevent stop-and-go traffic conditions.
How many miles does a spark plug last?
Most OE spark plugs have a life of more than 100,000 miles, thanks to electrodes that contain precious metals like platinum and iridium. OEMs consider the spark plugs a part of the emissions system on most modern vehicles. If the plugs fail sooner than the recommended interval, it’s important to solve the problem before installing new plugs.

Why is my spark plug Brown on my Kawasaki?
If the plug is brown or light grey your can assume your engine is in good condition and the spark plug is functioning well. Even when a plug is in good condition small deposits will accumulate. This is normal. There are many different causes of spark plug fouling.
Is it OK to foul a spark plug on a dirt bike?
If it’s properly jetted, you should never foul a spark plug, assuming your engine is in good running condition. If you want to go the easy route (well not really!), just ride the bike harder.

What to do when spark plugs get wet?
In this case, the best thing a driver can do is either wait for the plugs to dry, or remove the plugs and clean them off. Wet fouling is less common on modern fuel-injected engines, but can happen due to a number of mechanical failures, states AA1Car.com.
When do spark plugs on a motorcycle go bad?
The bigger the engine your motorcycle has, the more likely you’ll run into spark plug issues because you’re dealing with more of them. The first common sign that your motorcycle spark plugs are going bad is if your motorcycle is misfiring.
How can you tell if your spark plugs are bad?
You can also look for physical signs on the spark plugs themselves which may include burn marks, broken tips, rust, and corrosion. Throughout my motorcycle riding years, I’ve replaced hundreds of spark plugs mostly because the motorcycles I restored required it.
Why does my dirt bike keep fouling spark plugs?
Incorrect jetting is one of the most common causes of plug fouling, but we’ll look at what the top reasons why your dirt bike keeps fouling spark plugs and how you can fix it before spending a ton of cash on continually replacing spark plugs.
Can a bad spark plug cause a rough idle?
A rough engine idle can be caused by bad spark plugs. What happens is the spark plug fails to ignite the gasoline in the cylinder causing more fuel than normal to leave the engine through the exhaust. The O2 sensor is then tricked into thinking that the engine is getting too much fuel when actually the engine is getting the proper fuel amount.

What does a fouled spark plug look like?
Spark plug fouled by excessive fuel will have dry, black, fluffy deposits on plug electrodes. Deposits won稚 have caked or lumpy deposits of oil fouled plug.

Why are my spark plugs Sooty and black?
Unfortunately, it is impossible to prevent stop-and-go traffic conditions. When a vehicle is constantly in stop-and-go traffic, checking the spark plugs regularly for carbon build up, which is a sooty, black material that builds on the spark plug can prevent damage to the spark plug and allow cleaning before problems start.
What to look for when reading spark plugs?
If you are experiencing engine problems, taking a look at your spark plugs is a good place to start. When reading spark plugs, you will likely find one of the following conditions: Normal. Carbon fouled. Oil deposits. Wet. Burned. Worn electrodes.
What causes spark plugs to discolor when running?
For gasoline fuels, the residuals of carbon compounds from rich mixtures of gasoline fuels can cause discoloration. Proper gasoline fuel mixtures for long endurance racing usually leave only a faint porcelain discoloration. However, discoloration can increase with more racing mileage.
Can a coolant leak foul the spark plug?
Modern coolants do not cause this type of buildup quickly due to the reduction of phosphate, zinc and other additives that can contaminate the catalytic converters. Unfortunately, it also means that drivers will run a vehicle with a coolant leak for several thousand miles while the plug becomes slowly fouled.
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.
Why does my spark plug keep sticking out?
These molecules like to stick to the hot spots in the combustion chamber and this includes the spark plug’s tip and insulator. Curing the problem will typically point to the fuel system and how the engine is breathing. If a fuel injector is clogged or sticking open, extra fuel can cause carbon problems.

What causes a hot spot on a spark plug?
Coolant Problems. The problem could be a leaking intake manifold or a head gasket, and the fouled plug might be localized to one or two adjacent cylinders. The burned coolant leaves deposits on the electrodes and insulator, creating hot spots that could cause pre-ignition and a misfire code being set.
What to do if your spark plug goes bad?
Oil fouling of a spark plug could be a symptom of a more serious problem. They should do a compression test and a leakdown test on that cylinder in case there is a mechanical problem that is causing oil to enter the cylinder. If this is the case, better to get it fixed under warranty now rather than on your dime later.
