Ignition Coil Test!!!

[Primodlt]

This morning on my way to work 2011 Altima suddenly started running/idling real rough. With no Check Engine light coming on. I did replace cylinder #1 & #4 coils a few months back. How can I test/check the coils with out a multimeter????

There's no good way to check them except swapping, and that doesn't help unless you have a specific cylinder that's misfiring. There are really only five things on an Altie which can cause poor running without generating codes, MAF, fuel pressure, cam sensor, crank sensor, blocked exhaust.
