My check engine light started flashing and I have what is an obvious miss. Shaking engine, can hear it in the exhaust. I'm gonna code it tomorrow but would like to know common causes. Plug, wire, coil?

Check out the wiring and measure the resistance of the injector should be 11.6-12.6 ohms.

I have been looking and so far its looking like a dealer item. But I am still looking I would try a pick apart or junk yard a new one is going to be expensive. Especially if it comes only as the whole power train harness.
