08 Aura XR Running Lean.

[wraith05]

Hi guys,

So my Aura has been running lean on both banks for the past months, codes are P0171 and P0174. I've already swap all four 02 sensors with new ones, brand new MAF sensor and while I was at it new spark plugs. No signs of vacuum leaks, took it to a shop and the guy said it might be a computer problem. I wanted to check if anyone have had this problem before I go check the computer which I'm guessing won't be cheap.
