ok so heres the run down...in october i bought a 91 GS shell from a guy in ohio which i had the B16 from my old car that i rebuilt to throw in it. (the motor ran PERFECT in the old shell by the way) so i got the swap complete and it had troubles running. so i had my mechanic swap out the fuel pump, clean the lines and tank because there was water in the gas, replaced the filter, and swapped the fuel rail and injectors. I replaced the spark plugs, wires, cap and rotor as well. Now the car runs but is dumping way too much fuel into the cylinders...as a result the plugs become very foul and causes the car to miss while driving. My CEL is on for a code 5 (MAP Sensor) and O2 sensor which i checked and double checked and it is hooked up correctly because i have a rywire OBD0 to OBD1 conversion harness. Now i replaced the map sensor with a know to be good one and it was still throwing the code. Me and my friend have checked EVERYTHING and cannot seem to figure out how it is spitting SOOO much fuel. can someone PLEASE help to get a minty DA back on the road!?????
