My car has a misfire and its just started?

Hello,

There are few combinations of misfire conditions, it could be steady or random, it can only happen at idle or under load.
A misfire may or may not trigger the check engine light.

Take a look at this helpful guide:

The misfire can happen due to worn spark plug(s) or bad plug wires. It can also be due to a faulty ignition coil, distributor cap, distributor.

The best course of action would be to look at these items individually and go through the process of elimination to find the issue.

I have attached testing and inspection procedures below.

Please let me know if you have any questions.
Thank you.
