Default CEL Flashing

I have been getting a blinking CEL on the top of 4th gear runs. There is no hesitation and the engine runs as smooth as always. I scanned and got P0300 code (Random Misfire). Did the usual checks for Spark Plugs, Spark Plugs wires, loose connections, Vacuum leaks, and injector’s leaks where all looked fine. My car is stock except for Halltech KB, Halltech Tune and Catless exhaust which all were installed two years ago without issues.
Any Suggestions guys !!

Thanks
Bader

hook up a scan tool and see what cylinder or cylinders are misfiring. or freezeframe data on a tech 2 will show you

Update

A small EGR plastic nipple connected to the intake manifold found broken. Interestingly it seems that it was repaired by the evidence of some glue smear at the same location. My engine was replaced 2 years ago due to a broken valve spring which basically ruined the whole engine. Now, I guess it is a good excuse to get one of those new FAST intakes
Thanks for the help guys
