The flashing CEL means that the engine is currently misfiring. I got that on my car as well when I was leaning out and playing with it.
What you may want to try is leaning it out just a little at 50% throttle and up. If that doesn't work then try richening it up just a bit in the same throttle range. I think you will need to put it on a dyno with a wideband O2 sensor to see what the actual problem with the AF is going to be. My problem is greatly improved, but it is still there a little bit. I will be running on the dyno next week hopefully to see what is actually happening.
