It's running super lean. Don't drive it like that

We can't figure out why it's running lean

Which motor are we dealing with?

Chevy 2.5

It's either vacuum leaks, low fuel pressure, fuel injector issue, o2 sensor or the pcm is going out

We have tested all of those and everything came up normal

What was the o2 reading? Or did you just replace it?

It was reading .05 so we replaced

.05 means it's reading super lean so it was probably correct. What's your fuel pressure at?
