I got a P0171 code for a while, system too lean, but the car runs good, no idle/acceleration problem. Bank 1 has too much air or not enough fuel. Brief explanation of the P0171 Volkswagen Beetle code and definition of P0171 Volkswagen Beetle is the bottom side.

The most important trouble code here and the real identifier that a vacuum leak exists is OBD-II trouble code P0171. On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1. (Or maybe used your own OBD scanner to extract the car faults). Does the exhaust smell raw gas, which would be an indication of too much fuel. I wanted to post this thread since I thought you all would find it informative.
