I have had two ingition coils fail within the tenth year of owning this car. They are giving a cylinder misfire error when connected to a computer. They can easily be preplaced by anybody with moderate mechanical skills.

The car horn keeps going off. Took it Honda Repair Shop. They thought they fixed the issue, but didn't. Took it back... They said couldn't find anything. Tonight at 11:15 pm it went off. Then again at 12:30am. It's waking up the neighborhood. We'd all appreciate the solution. I'm taking the car back in the morning. If anyone has knowledge of the solution, please let me know.
