Cylinder three misfire

Hello thanks for using 2CarPros. the first thing to check on that number 3 cylinder is the ignition coil. When they heat up is most likely when it will act up, we'll start there. Here is a guide to help you check the coil. If you go to step number 22 in this guide, you can check the spark with a test light. If it's weak, compare it to a known good coil on the car.

Here is another guide to explain misfire issues and potential causes:

But check that ignition coil first and see if it has weak spark while it's acting up. Maybe take if for drive and get it hot, then run the tests. Another very fast test is swap the ignition coil to a different cylinder and see if the misfire follows to that cylinder. Hope this helps, let us know the results. Thank you.

Hi Larry

I fixed the links so they work. They had a "." At the end. Please recheck. Please run down these guides and diagrams and report back.
