Can multiple ignition coils go bad?
There is a tendency, but it may not happen, that replacing one coil will cause another one to immediately go out. If your 18 year old car has just lost an ignition coil, chances are the others are near the end of their life expectancy as well. You do not have to change all the ignition coils at the same time.
How often should ignition coil be replaced?
The ignition coil on your car is supposed to last around 100,000 miles or more. There are a number of factors that can lead to this part become damaged prematurely. Most of the newer cars on the market have a hard plastic cover that is designed to protect the coil from damage.
How much does it cost to replace an ignition coil?
While the price of replacement ignition coils varies widely, on most vehicles, it ranges from $40 to $300 for parts. If you have a mechanic do the job, you must pay labor costs. These likely depend on the design of your engine and the location of the bad ignition coil. The mechanic will be able to clear fault codes after the repair.
What happens when an ignition coil goes bad?
Your car’s ignition system is responsible for combusting the compressed fuel and air mixture inside your engine’s cylinder. The resulting combustion moves your pistons, which in turn moves your crankshafts which powers the car to move forward. Over time, your ignition coil could go bad, in which case you will need to replace it.
Can a plug and play ignition coil be replaced?
Many ignition coils offer a plug-and-play design, making them easy to replace. If your vehicle has this style of coils, even a relatively new DIYer can likely handle the replacement without professional assistance. Still, some coils are hard to access. If you do the job on your own, though, you only pay the parts costs.
Can a 2 cylinder coil pack go bad?
Usually one coil pack feeds two cylinders. If 2&4 are serviced by the same coil pack, then I would replace only that one IF it is checked and is in fact bad. They are pretty reliable and should last he life of the vehicle, but occasionally one will go bad. I really think the problem is something other than the coil packs.
