2000 Mazda Protege 4 cyl Front Wheel Drive Automatic

The vehicle has a miss the mechanic have changed cam and crank sensor the mass airflow sensor is ok. They have searched and searched but can find nothing
even the throttle body was also checked. However a reading of the mass was 102, 103 and 113. When it was tested again all was well with no fault. What next to do I am frustrated. And getting financially exhausted. Need help thanks.

Sir I thank you. Where is it located and its appearance. Have little or no knowledge of car repairs. Ps at 59-60km it feels as if it is not getting fuel after that its OK. Mileage 181727 model BJ 5P

Testing individual components does not isolate shorts or opens. Perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance, unless stated otherwise in test procedure. Use ohmmeter to isolate wiring harness shorts or opens.

IAT sensor is part of Mass Airflow (MAF) sensor. Disconnect MAF sensor connector. Using ohmmeter, measure resistance between MAF sensor terminals "C" and "D". Resistance should be 2210-2690 ohms. If resistance is not as specified, replace MAF sensor.
