need some help: fault code P0174

[Jan777]

When I start the engine the yellow lights go on. The search for the fault codes gives me this:

P0174 - Powertrain
System too Lean (Bank 2)

I can deleted the fault codes and switch off the yellow lights. But when I start the engine the next time, I get the same again. I do not see any difference in power, fuel consumption, sound or behavior of the engine.

What's the problem? Anyone got experience with fixing this?

thanks

Start by looking for any cracks on the air intake side. Check for vacuum leaks, maybe a hose came undone while working on something else recently?
You can also try cleaning the MAF sensor.

i have same issue, been battling it for weeks now, its bank lean condition, and could be caused by a mtriad of things, have cleaned maf and TB, no change, my LTFT bank 2 is 36% while bank 1 is 16%, very high values, have you checked yours?.

am leaning towards a fuel pressure test now, to see if my fuel pump is failing, bought the kit but have not seen where to hook it up:dancin::dancin:

keep me in the loop if you have gotten closure
