Your are there I am not, you said O2 sensor was bad I was saying replace all 3 because of the 30+ LTFT

If you have a new O2 the swap sides and see if problem follows new O2 or stays on bank

 

good idea. But what the **** did i find? Idk what this is but i just found it. idk what its connected to

 

It looks like your vacuum leak. Hard plastic vacuum line. Trace it back to see where it comes from. Most likely controls your air vents. If you can only get air to come out of defrost would be a good indicator.

 

Yup only air through defrost but that wouldn't be causing my lean codes though right? ):

 

Thats where the line is coming from is under those two thing where i circled. I have no idea where its supposed to hook to.

 

look at the bottom of post ron and see what i found

 

Your right only through defrost would that cause my lean codes though?

 

Yea i connected it back and all vents are back but that was a coincidence because i think my o2's are bad thats why im still lean

 

Anytime you have a broken vacuum line, your engine is going to suck in more air than it thinks it's getting. The only question is whether that particular line can allow enough air in to cause a lean condition. Possibly and it only helps to fix it.

 

Thats the thing it was never broke in the first place i just discovered it broken this morning. when all the vents worked i still had condition.
