Everyone knows that there's alot to check with when it comes to these two lean codes: (P0171/P0174). But some vehicle may have very specific location as usual for this particular issue. And I wonder if anyone ever experienced this lean problem on the same car mentioned above, how do they resolved it. And how do I test the air mass sensor to see if it's working properly after cleaning it.
have the same problem?
