rhampton- first thing to do is stop changing things if you're not sure . Do you know what you changed?

It would help if you would please post the numbers from EPA, D/R, EXP, N-PI, and N-TH. I'm assuming you're not using the Idle Up switch while you're getting it sorted out, but either way, it will be easier to make suggestions if you can share what your current settings are. If you're having it lift off too abruptly, the answer is probably going to be in one of the above menus.
