What is the easiest way of determining if your car is running rich or lean

If your car is running rich, it means that there is too much fuel being mixed with the air in the combustion chamber. This can cause a number of problems, including:

Decreased fuel efficiency
Increased emissions
Engine damage

If your car is running lean, it means that there is not enough fuel being mixed with the air in the combustion chamber. This can also cause a number of problems, including:

Decreased power
Engine damage

There are a few different ways to determine if your car is running rich or lean. One way is to look at the spark plugs. If the spark plugs are black and sooty, it means that your car is running rich. If the spark plugs are white and dry, it means that your car is running lean.

Another way to determine if your car is running rich or lean is to use a scan tool. A scan tool can be used to read the data from the car's computer, which can include information about the air/fuel ratio.

If you are not sure if your car is running rich or lean, it is always best to consult with a qualified mechanic.
