Flashing Check Engine Light

[2001 Camaro SS]

A flashing check engine light appears on the dash of my 2001 Camaro SS.  I looked in the owners  manual and reads that there has been a misfire condition has been detected.  My mechanic of long time just relocated and I have no idea where to start.  Any suggestions on what the problem can be.  I'm thinking spark plugs and spark plug cables.  Any feed back is greatly appreciated.   Thank you.

Stop by Autozone & have them put it on the scanner. Maybe something simple.

When was the last time your plugs and wires were changed?

Also, Have you ever had your injectors cleaned? you could also have a injector problem
