helping a friend do his LS swap. obd0 LS into 89 hatch OBD0 running stock harness to a PR4 obdo ecu..car starts but runs rough and shoots out black smoke...took out plugs and 3 and 4 cylinders are soaked in fuel......1 and 2 was not soaked but i could still sell it. car is running way too rich. also idles at about 1500....clean IACV already so i ono?

i checked for spark in all cylinders, #2 has no spark......vacumn at idle was about 10in. i have no idea of what it could be? no CEL....i think if it was a MAP it would nout cause that right? im thinking maybe cap for no spark? 02 sensor for the rich? car warms up and still idles high, and dumping out blakc smoke....help

 

no one with suggestions?
