Q: Running Lean

asked by on September 10, 2016

Car was running sluggish and check engine light came on. I went to get a free code pulled and it said Air Mass sensor. So I replaced it. Then it did it again. I took a look and saw the air intake hose just under the windshield had come off the big plastic part. I put that back in and it ran much better but, the check engine light came back on. Now the codes say, P0171 system too lean bank 1, p0101 mass air flow circuit range/performance problem (this is on there twice). It also says it is a MAF sensor wiring. I am pretty good at fixing stuff on my own if you could give me any tips. I have not seen any holes in the hose or anything like that.

My car has 104000 miles.
My car has an automatic transmission.
