Its the weirdest thing that i have ever felt. There are no codes stored. It has a mind of its own. The differance from when it feels good to when it feels bad is from a 12.63 @ 109 to a 13.21 @ 103. It will change from minute to minute. Any ideas ????????

My car does the same thing! Its driving me crazy! Only I don't know of its related but my fuel pressure drops with the throttle.
I have to reset the EEC once a week, because as the EEC learns how to run the car it seems to make it run worse.
