i have had a mini me swap for about a month now. i'm getting code 43 since everything was done, which is the code for "fuel supply system problem". i'm using my stock a6 block with a y8 head. i'm converted to obd1 and am using a virgin p28. i also have a rough idle most of the time, it's hunting from around 1100rpm to 1400rpm. it's not the iacv, because i've tried 3 known perfect iacv's and i still have the same issue. i've read that the differences between the p28 and the y8 ecu(p2p) is that the fuel maps are completely different, making my motor run rich at idle and lean during vtec. is this the reason for both of my issues? code 43 and my surging idle? thanks a lot
