I was driving home and all the sudden I get a flashing engine light and then it turned solid. I made it home keeping my RPMS low, and once i got home I checked online and everyone says its probably coils and spark plugs.
I ordered all new coils and spark plugs installed them deleted the codes and still having cylinder 3 miss fire. P030 code
What else should I do I erased the codes numerous times and still getting a flashing check engine that turns solid.
Start up has rough idle and rpms stutter

Possibly a dirty fuel injector.
Also perform a cylinder compression test, may reveal a bad cylinder.
Flashing check engine light means unburned fuel getting into catalytic converter, don't drive.. because what destroys a cat , raw fuel. Just because it's misfiring does not mean the injector stops working
