help!!!! 2 honda pilot's with check engine lights on
 

Hi-

I have a 2017 Honda Pilot with trouble code (blinking) P2654 and a 2006 Honda Pilot with a pending trouble code of P0303.
Can anyone help me figure out the problems with my cars please?
The 2017 I still am paying off so I don't have a ton of money to dump into these vehicles.
I am at my whits end and ready to sell them both.

Any suggestions would help. Thanks!

You have a number three cylinder misfire. Need to fix that or you will ruin your catalytic converter and that will really cost you money.
Switch coils around and see it it moves to the other.

If I switch coils around, do I have to disconnect the battery?

How much do you think it would cost if I took it to a repair shop to get fixed?

Could it just need spark plugs instead of a new coil?

Swap and see what you get. Don't need to disconnect the battery.
