How can I check it?

 

I also have checked the car with an exhaust gas analyzer and everything was pretty good (when the engine is warned up and at idle).

 

The short term fuel trim (stft)a long term (ltft) should be options for values you can monitor as live data. You may have to Google for how to do this on your particular scanner. Both values are necessary to get the total fuel trim.

Once you get the valuesavalues idle, raise the rpm to around 2000 and let us know what kind of values you.

This can help eliminate some causes of our engine performance.

 

Still having the issues? If so,, I posted a service manual earlier today, same one that dealers use ,, I would advice not to replace any more parts
go to the fuel & emission section on the book and start the eliminating process by troubleshooting the complete system that could cause the issue
,,ECT, IACV etc etc ...

Thank you guys. I will try to to check stft, ltft and use a service manual to fix this problem. If i will figure something out will let you know.

 

In spite of what you've checked, my money is still on either the Idle Air Control Valve (IACV), or low coolant level/air in the cooling system.

 

I'm still trying to manage to fix problem but unfortunatelly nothing helps. Today I cleaned the EGR Valve. Check engine error is: P0141 HONDA (Oxygen Sensor). Here are 2 videos how car surges:

Any ideas?

 

Have you done a coil and injector firing test? Seems like something is missing on the spark side or igniting side.

The P0141 would not cause your issue but at some point needs to be addressed. How long have you had the code?

 

I see in your second video early on that the power steering pulley is slowing down for a moment. Does the alternator pulley behave the same way?

 

Yes, I did, but when the engine wasn't warm. Maybe will try to check them while the engine is hot? I have had that code since I bought the car so it is like a few years.
