Thread: P0171 after installing headers

What I sometimes think crazy is that I can pull that you may have pulled a battery cable out of the air.

Maybe you were sleepy when you typed this? It doesn't make grammatical sense. Anyway, the p0171 is still completely gone, and I am left with the p131 and p140 that I started with. As previously stated, the p0140 is not an issue because I have the rear 02 disconnected. But how do I go about getting rid of the p0131? The wiring between the sensor and cables, as well as the extension, all look good. Suggestions?
