Q: Engine light having P0171 code
This summer my car's check engine light came on with P0171 code and I experienced lack of power in multiple cases. When I took it to a mechanic, they found a rupture in the valve cover and replaced (cost me $600 total). However, the engine light still comes back on every now and then (goes away sometime after I fill up the tank to full). How much would it be to actually fix the issue?
