Spark Plugs

August 25, 2017

Engine control computers precisely time when fuel is injected into the engine and when spark plugs fire. Unless something's wrong, spark plugs just don't foul like they used to.
Electricity from the battery goes into a coil that allows power to build up to anywhere from 12,000 to 45,000 volts, depending on the vehicle. The engine management computer tells the coil when to release the power to the spark plug. The electricity travels through a wire from the coil to the spark plugs. At the top of the plug, a spark jumps between two electrodes and ignites the gas in the combustion chamber. Some engines have more than one coil. Coils wear out and need to be replaced occasionally. Also, spark plugs and spark plug wires can wear out and need to be replaced. If you are experiencing an engine misfire, we can check the spark plug condition for you.

Please just give us a call and we will set you up with a good time for you to come in and get it checked out.

Thank you!
