Toyota MR2 Problems

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.

Got a Supercharged Mr2 that has idling problems. Sometimes the rpms stay still and sometimes it goes up and down and eventually dies. No misfiring happening like other people but still need to replace. Already took it to someone to tune the sensor.
