Went to go do emissions for car, went in with no check engine light for about 2 months. Failed the test! After I got the car back the car had the p0171 code, I go home let the car cool down for couple hours then start it up another code shows up p0304. How can I fix this and if I need to put a video on youtube to post the link here I will do so. MAF is working and has been cleaned already.
have the same problem?
