Re: Check Engine Light WILL NOT GO AWAY

According to alldata. The P0171 is Fuel Trim System Lean Bank 1, and the P0174 is the Fuel Trim System Lean Bank 2. So basically your running lean. I would check your oxygen sensors. See if you have any vacuum leaks anywhere, etc etc. But thats what those codes are.
