Car ignition coils can be a pain to replace. Not only are they expensive, but they can also be difficult to find. In fact, it’s not uncommon for dealerships to charge you more for a coil replacement than the car actually costs. If you’ve been struggling to get your car in the shop and notice an odd noise when you start it up, it may be time to replace your ignition coil. Here are some tips on how to tell if your ignition coil is bad and what to do if that’s the case.
What are the signs that your ignition coil is bad?
When it comes to your car’s ignition coil, it’s important to keep an eye out for any signs that it may be damaged. If you notice any of the following signs, it might be time to replace your ignition coil:
-Your car does not start as easily as it used to
-You have difficulty starting your car in cold weather
-Your car has a rough idle
-Your engine sometimes sputters or stalls when you try to start it
How to test your ignition coil
If you’re experiencing trouble starting your car, it might be time to test your ignition coil. This is an easy DIY repair that can help diagnose and fix the problem. Here’s how to do it:
1) Remove the Phillips screw on the side of the ignition coil cover.
2) Lift off the cover.
3) using a multimeter, check for continuity between each wire in the coil. If there is no continuity, it likely needs to be replaced. If there is continuity, then it may just need a new fuse or poor connection at one of the terminals. Replace as necessary.
What to do if your ignition coil is bad
If you’re experiencing intermittent problems with your car’s ignition, it might be time to have the coil checked. In some cases, a bad coil can be the culprit behind these issues. Here’s what you need to do to check your coil: Remove the spark plugs and use a voltmeter to measure the voltage at each plug (4.8-5.2 volts is okay). Compare the readings to those in your owner’s manual. If one or more of your readings falls outside of acceptable ranges, it means that your coil is probably defective and needs to be replaced.
