Ignition Coil Replacement Service & Cost

What is the Ignition Coil all about?

Ignition coils transform low voltage electrical power 12 volts D.C. to high voltage current 50,000 volts D.C. or higher. The spark generated by the ignition coil ignites the fuel and air mixture in the engine that enables the car to start and run smoothly. If an ignition coil is not working properly, no spark will ignite the air fuel mixture, causing a misfire. A bad ignition coil can severely damage the engine or catalytic converter.

If your car is equipped with “coil over plugs,” then it is recommended that you replace the spark plugs. If your car uses a single coil for the ignition system, it is not necessary to change the spark plugs.

Ignition Coils

Keep in mind:

  • A malfunctioning ignition coil can cause damage to the ignition wires and spark plugs; these components should always be checked when the ignition coil is replaced.
  • Ignition coils are often damaged by other parts that leak hot oil onto the coils. If this is the case, the leaking part should be identified and replaced.

How it's done:

  • Test the ignition coil(s)
  • Remove and replace the faulty coil.
  • Inspect spark plugs and electrical connectors.

Our recommendation:

To keep the car’s ignition system in good condition, you should keep up with the regular maintenance of the car as suggested by the manufacturer. Your mechanic should measure the resistance in the spark plug wires. The wires with too much resistance can cause an ignition coil to fail prematurely. The Check Engine light will come on if the engine is misfiring (the ignition coil may be faulty). To avoid costly future repairs, do not drive the car for too long with a bad ignition system.

What common symptoms indicate you may need to replace the Ignition Coil?

  • Car may not start.
  • Car may not run smoothly (engine misfires).
  • Check Engine light is on.

How important is this service?

An ignition coil turns low voltage into high voltage, which is then used to ignite your vehicle. After the ignition coil has converted the low voltage into high voltage, it creates a spark, which lights the fuel, and powers the engine. This small explosion is responsible for turning on your engine, and for keeping the engine running. When the ignition coil is damaged, it is unable to create this high voltage spark, and your engine will have a hard time running, or may not run at all.

James did a great job replacing my radiator. He called to see if he could come a little early which worked out great. He was very professional, cleaned everything up after he was all done. Asked if I had any question about anything on my car and gave me a few pointers about an issue I was having with my hood shocks. I will for sure be calling him again when I need any service done to my car. I have already recommended him to 3 of my friends looking to get some work done on their cars.

I have to say that I was a little apprehensive at first. Being a Mercedes driver, I've come to know that servicing these cars are anything but normal. So in asking I found that Peter approached this job different from the dealer. My mind was set to rest with a detailed explanation from Peter. He does excellent work with excellent cleanup as well. I was very happy with the outcome and also pleased that he was on time, early actually and very professional. I will be using him again I'm sure. Michael C
