Diagnosing OBD Errors P0301-P0303, P0305 on 2005 Honda Odyssey EXL
My 2005 Honda Odyssey EXL is still running rough after checking and adjusting the spark plugs and replacing the ignition coils with new ones. I even swapped ignition coils from front to back. I noticed that when disconnecting each coil wire connector, the idle was not changing when I pulled the front wires. However, the idle changed when disconnecting the back coil wires.
Not sure what to check next. I read on another post that I may need to drive the car at least 30 minutes to allow it to re-familiarize itself to the new coils? Is that right?
