I recently bought a 90 240sx. The previous owner had installed rx7 injectors, an rb20 maf (I think), and ran it on e85 without any tune.
I pumped out the remaining e85, installed new oem injectors, new oem maf/pigtail, and changed the spark plugs (old ones were black).
It still is running rich and misfiring. I have also replaced the thermostat and coolant temp sensor.
I couldn't find a vacuum leak with tb cleaner and have no idea of what to do next.
(also just checked ecu codes)
ECU Codes:
12- Air flow meter circut
13-Engine Temperature Sensor Circuit
41-Air Temperature Sensor Circuit
