Good day. The screenshot shows the DTC retrieved after scan, when the engine is cranked and running at idle, in the next few seconds the idle speed will increase to about 3,000 RPMs, and it the PCM will set these codes, the spark plugs are checked, ignition coils also checked, all the vacuum hoses are checked, still doing the same thing.
Please tell me what the cause of the problem could be. Thanks.

Hello,

Those random misfire codes can sometimes be tricky to diagnose. This could be due to a number of components.

I have attached the troubleshooting guide for the code P0300 below. Follow those steps, as that can help you determine the issue.

Let me know what you find or if you have any questions.
Thank you.
