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 Read more...

Fuel Injectors

At Weldon Spring Automotive, we start with a visual inspection of the components for signs of damage or leaks. If the system has A/C dye in it already, we can hopefully see where the Read more...
