Well for one the only difference in the lex afm and stock afm are the size, the electronics are the same so take the electronics and put them in your stock housing and run it like that until you get the supporting mods for the lex afm. such as the 550cc injectors, afpr, and walbro fuel pump or 2jz gte fuel pump.
As for you idle problem and rpm fluctuation check your codes sounds like your tps may be out of adjustment. your gas pedal can be adjusted by the throttle cables on top of the cam covers.
