Bank 1 And 2 Too Lean

[dietz4ibanez]

Alright I have new O2 sensors on banks 1 and 2 they are both sensors number 2. Am I getting these codes cause I more than likely need to replace sensor 1 on bank 1 and 2?

 

I can notice a lack in fuel mileage.

I would check that you don't have any vacuum leaks first. Both would unlikely bad at the same time.

Alright! I will check that right away cause I bet that you are right!!!

Yeah most likely it is a vacuum leak or and intake leak use some brake clean and spray around. it makes it easier to find the leak

Welp that was the prob. stupid k&n box and mass air connection just doesnt was to reach or hold together like it should. Tried to make some adjustments so that it holds this time! Light came right off!!!!

Thanks Guys
