Don’t think my simple code reader has MAF data
But I did clean it a year ago with MAF cleaner
I may just have to resign myself to the fact that the cat is broken but I won’t replace it as long as I can keep clearing the code and it passes smog
The car is 18 years old and each smog check is 2 years so perhaps I won’t be keeping it beyond the next cycle because other issues may pop up due to the car being so old
Will try to sell to an enthusiast
