Intermittent CEL
 

Hoping someone else may have experienced this and could shed some light. I'm getting code P2187 indicating that air/fuel mixture is too lean at idle (had previously been getting P2177, same indication). The thing is it's difficult to take it seriously because the car runs perfectly and the CEL comes and goes without me trying to do anything about it. Since the car runs so well I don't know what I could even try but it's just annoying to see that CEL come and go.

Check your intake hose for a tear or crack.
