I recently did a dpfi to mpfi swap on my 91 dx. All went well and worked all of the codes out but one. Code 10 IAT sensor circuit. Come to find out the 5V reference wire was bad. I ran new wire to the sensor, verified my repair and it eliminated the code. I reset the ecu, fired the engine up and now I have a code 3 MAP circuit issue. They are unrelated circuits acording to alldata. What went wrong? Im running so damn rich I can breath in the car
