service engine light comes on and off. So I had this light come on and then checked the codes and it had 2 showing up which were the same. This is the results from the odbii website.
DTC Description
P0174 Fuel Trim System Lean Bank 1,2
VIN Digits 2
Manufacturer 3
Division 4
Body 5
Series 8
Engine 10
Year
So I changed all the 02s out and erased the codes and now the light is back on and off, checked the codes again last night and same code. Any ideas what to look at next? A couple people I talked to might think it is an air leak since it's showing up lean. Now only one error is showing up P0174 being bank 2 being lean.
