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?

Do you
have the same problem?

Could be injector bad or clogged spark plug coil etc. Please get me the exact code numbers not code descriptions?That would be a great starting point.

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