every thing passes just fine except the oxygen level. its running to lean. I am not sure what to do or how to fix it. according to the paper which they give you 10000 answers as to what it can be I dont know how to narrow it down. I have had them reset it and drove it around for 112 miles and still wont complete all the cycles it needs to reset it. any advise? Just recently had an oil change. did a gas aditive to clean the tank ( well the gas lines )

You haven't fixed anything by clearing the codes. All you did was erase all the important stored data the computer had accumulated.
We need exact code numbers before we can even begin.
