2008 Honda element - P0301 cylinder 1 Misfire - Light Flashes then VSA light

What is your question?

1. I changed spark plugs and air filter 2. I changed the coil pack on cylinder 1 3. I tested cylinder compression - checked out 4. I changed the fuel injector on cylinder 1. Things to note. I clear the code and the car idles smooth around 1200 rpm for30 seconds before the rpms dip to 700 and the cel flashes again. When I remove the plug to the MAP sensor, the cel no longer flashes.

What makes this problem better or worse?

Clearing the Code on initial start
