Air Flow Sensor May Fail at Higher Mileages on Toyota MR2

Problem Description and Possible Solution

At higher mileages (125,000+) the mass air flow sensor may cause the vehicle to idle rough, run rich and even stall. Our technicians recommended to replace the mass air flow sensor with a factory unit because the aftermarket units have very mixed results.
