Engine cylinder misfires?

Thanks for the help. I did a "drop test" and found one cylinder bad, changed the coil pack and fixed the problem.
For thoes that would liek to know how.
With your car started start pulling the plug to your coil pack one at a time. You should hear your engine start to die. If you dont hear any change in engine idle that cilinder is the problem. Continue to all cylinders to make sure its only one cylinder. From there you have the plug, the coil pack, and the wire. If your plugs look good change the pack its $90 from honda.
This worked for me on my 2000 accord V6.

Thanks

I have an Accord with 188,000 that just started acting up. The check engine light came on and started blinking. When I pulled the codes I got 5 - P0300, P0303, P0304, P0306 & P1399.
The car had it's timing belt, altinator, battery & plugs changed last year. The car is ideling something awful and you can smell gas. The dealership recommended replacing the coils. Can the 3 coils go bad at the same time? Is there one coil for each spark plug?
Thanks!
