Just Bought a 2002 accord with 56,000 miles. When cold or in the morning, during idle the engine missfires. After it heats up, the missfire disappears. It runs great afterwards. The power seems a little weak.
Whenever i press on the gas pedal, it seems i need to press harder to make the car move or it needs to have a higher rpm before the car moves.
Other than that everything seems great.

Does anybody know whats wrong and where do i start looking?

 

Lets start with a leak down test when cold That test puts compressed air in cyl and look for air in cooling sys google leak down test or go to a big box parts stor and rent one with the info. you need

 

Thanks Joe! I will look into the leak down test!

 

Misfire only at idle? I would check for vacuum leaks, then the ignition system.
