I have question for my vehicle. I got a code for p0171 lean condition bank 1, I tried checking for vaccum leaks and replace the intake manifold gasket, clean the MAF sensor. Clear the code but still coming back, my question is what else could be or cause this issue? The vehicle has 188000 miles, when I bought it everything was okay but the code came on once the winter hit here in Texas it runs fine it the RPM doesn't go up and down like crazy or anything, the car starts right up with not issues, it doenst shake or struggle, any ideas?
