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.

Tien

I made an appt. for Tien to come by and replace the fuel pump for my no start diagnosed by him through the inspection I had a few weeks earlier. Tien got to work on the car immediately on arrival. As in many if not all jobs, it turned out to be a more complicated than expected. In the process of changing the fuel pump, he discovered that the new fuel pump was slightly different than the one being replaced and the wiring would need to be adjusted somehow to be able to use the new one. It was amazing to see as he used his knowlege and experience to make the necessary adjustments to make the part work! He could have taken the "shortcut way" which a lot of mechanics would have done. When he removed the old fuel pump, it seems that only the fuel hose part was damaged beyond repair, but the rest of the unit was intact and probably still working. He could have maybe just changed the hose part and left the rest of the old unit as is, but decided to replace the whole unit if he could, pending the wiring adjustment mentioned above. Thanks Tien for a great job highly recommend you to everyone!

Patrick

My 2007 Cadillac SRX AWD V6 was pinging on acceleration, had lost engine pep and the gas mileage had dropped to about 10 miles per gallon. The car has 97,000 miles on it and Cadillac recommends changing spark plugs at 100,000 miles. I called Cadillac and got a quote of $ 550. Wow! I called your mechanic and got a quote for $ 299.00. I asked for Patrick, who I had used before. Patrick came and and did a pretty involved job disassembling the top of the engine to reach the spark plugs and replaced them in about 3 hours. Patrick noted that the old plugs were very worn and that the spark plug tubes and the spark tubes had oil at the bottom of them. He told me that might be because the seal at the bottom of the spark plug tubes had failed, allowing oil from inside the valve cover to get into the spark plug tubes. I did some research and found that these seals failing is a relatively common issue in SRX's as well as other vehicles. The seals are not expensive but it appears that to replace them, the top of the engine would need to be disassembled again plus the valve cover on each side would also have to be removed, Then the seals could be installed and everything reassembled. That's most likely an expensive job. I drove the car after the new plugs were installed. Quite a difference. The car has its pep back, the mileage is starting to rise back to normal levels, and although I still get a slight ping at times, at this point it is about 90 % less than I was getting. My question is if I do nothing about the spark plug tube seals, will my issues return? Notes about this indicate that at some point the spark plugs are fouled enough to cause engine error faults and misfires if the spark plug tube seals are not replaced. Now I have to decide if I want to spend the money to have the new seals installed or take my chances and see what happens. If you read this Patrick, I would appreciate your best guess. Patrick is a very good mechanic. My dad ran an auto parts store, a garage and a machine shop for 25 years so I do know a few things about cars and know a good mechanic when I see one. If you need an excellent mechanic who is also honest, look no further than Patrick.

I was quite satisfied with the fact tha Jeff left the bedside of his wife to attend to fixing the problem with my vehicle. He was appropriately apologetic and pleasant. Time will tell if the service holds up.
