90 crx dx with a jdm d15b throwing codes 3(map sensor) and 14(iacv) possibly something related to each other... i dont have the car yet im buying it tomarow and i dont know what ecu he is running... i posted in the crx forum but i didint get any tech responses, and i know the d15b is a comon swap for the 92-95 civics

it also runs really shity and bucks like crazy unless you are just touching the gas but it runs smoth on WOT

anybody get these same 2 codes... something related or does this sound like an electrical problem sensor problem or vaccume problem???
