    I'm getting my engine motor light on. When I get to my mechanic, they use a code reader looking for codes P2187. They told us about System Too Lean at Idle Bank 1 and 2. First they tried to erase the code and Engine motor light comes off but Eco mode light comes on. After few minutes Engine motor light comes on again.

    I had the same. Replaced OCV valve, and also all 4 O2 sensors (105k. Snd they were cheap). Eco mode works again, and 2 mpg improvement.

    Did this happened when you were low on fuel? I got those codes when I was low on fuel and used the GAP tool to prime the fuel pump and codes when away and never came back.
