I have a 2000 Honda Accord and I'm having a lot of problems now! When I connect the scanner it reads multiple cylinder misfiring? I changed the spark plugs back to the original ngks , and I thought it would fix the problem, and it's still misfiring. What do I check in order to fix it?

Hi there,

Check for intake manifold leaks, the wires, the coil and low fuel pressure to start with. These can all cause multiple misfires as they affect the whole engine.
