Any ideas on my situation? I have a P0171 that has come on ever since my fuel pump, turbo, injector, ground mod install. I have swapped the injectors, and it is still there. It comes on after about a week or two and stays on until I clear it. The car runs fine; I have not had any running issues or anything. It tends to also come on while idling at a stoplight.
I have a FMIC and a perrin short ram, and the clamps have been checked on those pieces.
Any thoughts that jump at you?
