P0171 Code
Hi all,
Due to them being cheap and having problems, I replaced the cutouts (in front of the mufflers, I believe past the cats) on my 96 LT4.
I used to consistently get a P0171 code when I had the valves closed, but it would clear after a while with them open. Now, after dong a pull with a buddy, it stays on pretty consistently (nothing crazy just 3rd gear to 6300 rpm and then 4th to same).
What do y'all think it is? I'm not seeing leaks around the intake gasket (but I will check more closely when I get the chance), and the issue from before makes me think it was the cutouts. This didn't happen before with the previous pair.
