I have a 92 Lexus SC400. Does anyone know what is the part number on the mass air sensor? I call the Lexus dealer and they give me the mass air flow assembly.

AIR FLOW METER ASSEMBLY Part Number is 22250-50030

If anyone what is the OEM sensor part please let me know.

did uget a OBD2 magnaflow cat? or simply a regular cat?

I don't know if the CAT is OBD2 OR regular CAT. Does it makes a difference?

Do you still have the MAF? I think my air flow sensor is going out on me. I would appreciated if you can sell me one of yours.

Thanks,

Pat

Do you have the instrument cluster?, climate control, air flow meter, EGR Valve, air compressor. let me know if you have any of these items and prices.

This is what I have done to try resolved the smog issue:

Install New PCV Valve

Cleaned air idle control

Cleaned throttle body

Did an oil & air filter changed

New Cat

2 New Oxygen Sensor (upstream)

Other minor issue.

No illumination on the idle needles

Heater turn on, it blows but no heat

TRAC Control light is constant on.

Aside from the issues, the car ran awesome.
