If your Toyota MR2 Air Flow Meter keeps failing the issue is most likely to much oil on a Toyota performance air filter, or to much blow by from the MR2 engine.
Use only Toyota OE quality replacement Catalytic Converters to keek your Toyota MR2 in the best running condition. DriveWire sells only California legal MR2 OBD-II Converters.
If your Toyota MR2 failed the emissions test due to high NOX, the EGR Valve is most likely the issue. If your Toyota is running rough or has poor fuel mileage, replace the MR2 EGR Valve and gasket.
Do not buy the cheap no name remanufactured or rebuilt Toyota MR2 electronic control units, as in our experience most of these ecu’s don’t even work right out of the box. We also carry programmable Toyota MR2 control units from AEM that allows you to custom program your Toyota MR2 ignition and fuel system.
The Toyota MR2 Oxygen sensor is a critical part of the emmision control system and should be replaced as soon as it fails. Make sure to check the Toyota MR2 diagnosics codes for proper replacement of the O2 Sensor.
