I still have a low rpm problem with my acceleration. A friend mentioned that maybe I am running to lean and therefore I run good in high rpms. If this is the case what would I have to check or replace to fix the problem?

clean your maf. If it's dirty it can cause your motor to lean out

Also, having a 200 have you done this?

Replace the fuel filter as well, if you haven't already.
