You can start out by finding out if all of you pistons are fireing.
The way to do this is unplug one spark plug at a time, while your
doing this look for a drop in idle. It the plug is fireing you should
see a drop in idle after unpluging the wire from the sparkplug. If no
drop then that may be your bad piston.
