That's the cleanest engine bay I've ever seen!

So I replaced all 3 oxygen sensors, the selinoids . And replaced the mass air flow sensor 3 times still getting the lean codes . I also put a new air filter in. I was told by two mechanics . That it has to be an OE part . Any advise ?

well if your buying super cheap that can be the issue but it doesnt have to be oe

I checked my MAF reading and holy smokes it is all over the place. Previous owner replaced the sensor with a cheap one.
