once again im asking if anyone has any ideas. here's the problem i recently swapped a d16y8 into my car (92 eg ) and i keep getting codes 5 & 15 ( map sensor & iacv) so i switched both of them with new ones 3 times, i then switched my obd1 wiring harness to an obd2 and i still have the same problem. now i just switched the throttle body, and ECU and i still have them.
now im wondering if i should change out the manifold or if something else could be the problem but i cant think of anything. so any ideas?
