i have a b18c1 in a crx, im using a b16a1 head and a obd0 pr3 ecu. the problem is that when i datalog i get a reading on the iat of 87-88 deg ferenhiet all of the time. i tried replacing the sensor, with a used one, and i still get the same reading. when i disconnect it i get disconnected from my logger but i dont throw a code and my idle starts surging. so i think it is seeing the iat but not sure. i also checked continuity from the connector to the shock tower and from the shock tower to the ecu pin c5 and c12. any ideas?
