I was told by the Smog shop that I was running too lean. They said that I wasnt getting enough air and the Air to Fuel was off by a bit. They said that maybe if I removed the air filter while doing the test it might help for it to breathe better. So I removed it and they ran the test again and the numbers came back 5x worse. I have to get 1.2 reading at the most, with out the filter it ran at 10.0-15.0, and I am currently at 2.08 with the air filter in. They said it might be the Mass Air Flow Sensor. I went to the dealer and they said that my car does not have one. I think it might be my O2 sensor. Can this make my car run lean? I dont want to change them out cuz the previous owner cross threaded the mofos. Where can I start fellas? Any suggestions? Thanks

Try cleaning the O2 sensor.. but isn't running lean too little fuel to too much air? I dunno why they'd want you to put more air in it; thats probably why the results came back worse. You want LESS air in your engine to make the ratio favor gas more.

Also, maybe the sensor thats in the intake? try cleaning that too
