Default how to test for bad coil with them off car.

Over the winter one of my coils must have **** the bed. car ran like crap onece it was taken off idle prolly due to the coil not being able to saturate and taek on teh load. so i switched my buddies coils onto my car and it runs perfect. my coils are off my car right now. i was jw if there is anyway to ohm out the coils to check for a bad one. if not i can just pop them back on the car and graph them with the TECH 2. would just be easier off the car.

All you can check is that it's not shorted or open, and that can change when it's under load and heats up.
