    I have replace plugs, wires, and coils...each one of those cleared the code for a few days and it keeps popping back up...the cylinder only misfires during idle, not sure where to go from here. Any help will be appreciated!

    Leak down? Compassion? Ac delco parts???? Oil or excessive fuel in cylinder and you need to monitor misfire counts is it dead or just injector problems
