How can I tell which one of my coils is bad? I get a high rpm sputter when i stab the throttle. No " check engine" light.

Get an ohm meter and check resistance across each ignition coil. They should all show very close to the same resistance as each other. If one is way out, good chance its bad. High speed sputter does sound like a lean condition as well. check your plugs while your in there.
should this be done while the car is running??
