I recently had my car smoged and it passed. My car drove fine. Later that day the check engine light came on. I went back and had the mechanic check the light it then pulled two codes: p0171B and p0174B bank one bank two system too lean. He cleared it and it soon came back on.
I read and heard it could be a few problems being; mass air flow sensor, vacuum leak, or just need a simple tune up!
since I had these codes pulled it has been almost 2 weeks and my car is now driving much crappier. It feels slightly shaky and the rpms are not kicking as properly as they should almost as feeling as a transmission may go. I cannot afford just to check the issue for $200 and not have anything fixed. Do u have a suggestion in what may be my problem?

A tune up I would say no way I would check3ck for proper fuel pressure then next look for a vacuum leak.
