Fix that code and maybe the problem will go away https://honda-tech.com/zerothread?id=468260

 

To check your code:
Pull the carpet on the passengers side floor
You can see a small clear circle, it should be blinking
(ex. ..... blink blink..... blink blink..... blink blink..... equals Code 2)
count the number of times the light blinks in a group.
When you have the number or numbers search for "ECU codes" here, you'll
find what the code means and the reason why.
Your engine problems are most likely related to this.

After you fix the problem remember to reset your ECU or else it won't know you fixed it.

Do this by either unpluging the negative battery cable and waiting about 5 seconds or removing the ECU fuse on top of the passengers side strut tower under the hood and waiting around 5 seconds.
This basic info should help you, let me know how it goes
