Hi All,

New to the forum. A friend of mine has a 2013 Chevy Cruze (1.4L) with the following codes:

P0171: System Too Lean (Bank 1)
P015B: O2 sensor Delayed Response - Lean to Rich Bank 1 Sensor 1
P1101: Intake Air Flow System Performance
P2270: O2 Sensor Signal Stuck Lean - Bank 1\, Sensor 2

I need to ask him what symptoms he is experiencing (I think maybe some rough idle, maybe loss of power).

His valve cover was leaking. Replaced the gasket. About to replace the entire valve cover as their is a crack in the plastic (i.e., its still leaking, found the crack afterwards). He's also previously replaced spark plugs. We'll be doing the coil pack when we replace the cover here soon. Aside from that, the car has ~130,000 miles on it and hasn't really needed much other work. Engine looked good under the cover (nice and clean, no sludge deposits or anything).

Has any body had these 4 codes all together before? What solved your problem?

Looking at what it could be, there seems to be a lot of options...MAF sensor, O2 sensor, vacuum leak, purge valve.

I was thinking of replacing the purge valve cause that's pretty simple/cheap. Could do MAF and O2 sensor etc. Just looking for a good place to start and see if anyone had advice or the same set of codes.

Thanks much.
