ok heres the issue, i have an F20B motor which ofcourse is OBD2B, I have a OBD1 P06 for it and conversion harness, but the preoblem is, when i plug in the P06 (I have a H22 map to start with) the car will idle kinda rough for about 2-3mins then go lean in no time, then we have to turn the car off, we are using a wideband O2 so we know wats going on with the A/F ratio. any clues as to y its acting like this, we even turned up the fuel by about 400% an it still goes lean, I have a CEL as well, but cant read it for some strange reason, could it be fuel related?? please someone help
