the check engine light flashes for a misfire, i would start with the common things first, plugs, wires, etc...check with your scanner if it has a misfire counter for the cylinders and see which cylinder is highest, and if the tune up dosent solve it, change the coil for the high misfire count cylinder

Sounds like an O2 sensor. Post the DTC codes you are getting.

You should not only be changing plug but confirming that the plugs are actually sparking. Check for Spark and Fuel on each plug and injector, then worry about the sensors or codes.
