CHECK ENGINE light blinking...What's up with that?
In an effort to break in the BOSS which now has 250 miles, I've been varying the RPM's, trying not to keep it at one engine speed for any prolonged period. On the way down to Monterey this weekend I had approx 130 miles and was working my way up the RPM "scale" and briefly held it at 5,000 for about 5-10 seconds when I saw a yellow flash at the bottom of the speedo. It was nighttime, so it caught my attention, but then it was gone.
Today, at 250 miles I was winding it up and got to 4,500, left it there for a few seconds, and then went up to 5,000, leaving it there for 5 seconds or so...and again, the Check Engine symbol came on...but didn't go away. It just kept flashing on and off for about 10 seconds, and then went away. What's up with this?
Engine is at normal operating temp, oil level is fine...... is this something that they just "do"?

It should have stored a code in the memory. I would go get the codes read. When the engine light flashes its a more serious problem that can damage the engine. when it stays constantly illuminated its usually a sensor issue. But when it flashes its detecting something more damaging then just a sensor. Like dead missfire, air to fuel ratio way off. Something in that nature.

CEL is a "yellow" color (RED colors are used to show serious problems- like an overheat) so while it's disturbing I don't think it's serious. I think with all the various sensors and other safeguards in today's modern engines your car would go into limp mode if it was serious.
You can throw a CEL just from refueling your car. I wouldn't lose sleep over it.

Is the port under the dash on the drivers side?

Port is under driver side. This car does have a propensity for codes. If it was a flashing CEL and it's gone, there's a better than even chance you won't find a DTC. Never had a car before that generated CELs that cleared themself. If it's gone and you didn't go into limp mode you are fine to drive it.
