Why do you suspect one. Do you have a misfire or check engine light?

The engine sounds like it's having a misfire, and the check engine light goes from being on to blinking and back to being just on again. This happened once before over a year ago, and one of the coils had to be replaced. I just want to know if there's a feasible way to check it myself before bringing to a professional.

You need an ohm meter to check it. Disconnect the wiring from the coil. You should have.8 OHMS at the primary circuit and 16,000 at the secondary. If either are at 0, replace the coil.

No, there really isn't a good way to test them without using a scope. Many of the failures are temperature related anyway. Get the codes read and that will tell you which cylinder. Then I would just go ahead and change the coil. It's not real expensive.
