hey Guys hadnt had a chance to get the OBD2 Scan done but the check engine light came back on yesterday so got it done at autozone P0171
was the code they say its either the O2 sensor or clean MAF sensor vaccum leak is also a possiblity, soooooo many possibilities .
I am going to clean the MAF sensor with electrical cleaner is that good
what else should i try
thanks
