You can test coils with an ohm meter, but that is a waste of time - they can test good but still be bad.
I just replaced all 3 coils on an '02 V6 Camaro. One or two were definitely bad. I only replaced the third because they were cheap enough and I wanted more peace of mind. Found mine CHEAP on eBay,
brand new and OE too. They are easy enough to replace, you might try getting a whole new set if you can find them cheap enough, otherwise, just buy 4, chances are you don't have 4 bad ones, but you will have a spare in case of future trouble.
