What does the ignition coil do? An ignition coil (also called a spark coil or boot) is an induction coil in an vehicles ignition system that transforms the batterys low voltage to the thousands of volts needed to create an electric spark in the spark plugs to ignite the fuel-air mixture. The number of coils in your engine depends on the number of spark plugs it has. When you turn the ignitio? it not only sends power to the starter to turn the flywheel and start the piston? crankshaf? etc. It also sends voltage to your ignition coi? then through the wires to your spark plugs. Your spark plugs take that energy to generate a spark that ignites the fuel-air mixture in the cylinder. The spark plugs are constantly generating a spark as the vehicle is running and as the pistons compress when the fuel and air are mixed. If a coil is not functioning properl? it will cause the vehicle to run rough. How do you know you need your ignition coil(s) replaced? Engine light is on Engine is misfiring Vehicle is running rough Issues starting the vehicle Poor fuel economy How is the ignition coil replaced by a mobile mechanic?

"I'm a big fan of this incredibly convenient service! GoWrench staff do a great job and respect your time, unlike the nightmare that is involved in visiting the dealership/auto shop just to get your tires rotated or oil change. I shouldn't have to lose a day of work, two times a year, just for regular maintenance & tire swaps -- and with GoWrench, I never have to deal with the patronizing, dirty, and time-consuming service at the car dealership or auto shop, again!"
