Boy, was I off base! Took it for a ride & noticed a bit of a rough idle. Then, CEL came on. Drove over to Advance Auto & borrowed their code reader. Code p0305 came up. Looks like I need new plugs?

I wanted to add. The CEL is flashing. Does that mean that the cylinder is not firing at all? Don't want to fry the cat!

Flashing CEL means a misfire is currently happening. Yes, that can destroy the cats if not immediately repaired.
