Re: CEL on 1990 GSX

Got a meter, they only had digital ones, and it is hard to read exactly what the code is, it goes through the numbers so fast. I think it's either the O2 sensor, or the MAS. I just had the O2 sensor changed a a dealership, so I think I might bring it back into them and see if the sensor they put in is bad. Any thoughts?
