I have an ef sedan that I converted from dual point to multipoint using a rywire harness... I have a d16y7 that has been converted to obd0 runnin off of an obd0 pr4... I am gettin a code 8 (TDC code)... I have looked everywhere and I cant figure out how to get rid of it... I originally had a d16a6 and it threw the same code in it the entire time I had it too

PLEASE HELP... thanks
