Mitsubishi io 1999 engine idle speed is not stable and misfire. Radiator fans are not run so engine is heated. How to do it pls reply me. Thanks alot. Im from Myanmar.
Error code show, 12 AFS, 14 TPS, 21 CLT, 79 TPS (main), 91 ETV system. I don't know where is that sensor located and how to test that sensor good or not.

Code 12- Air Flow Sensor. Sensor at air cleaner.
Code 14 - Throttle Position Sensor. At throttle body
Code 21 - Engine Coolant Temperature Sensor. At end of cylinder head.
Code 79 and 91 are not listed in the OBD-1 code table. I would need to have the OBD-II codes to know what they really are.

Since the codes are not directly related, clear the codes and retest to see if all of them comes on. Check for loose connections and for the cooling fans not working, the ECT could be the one likely to cause the problem.
