Hi all - New to forum.
Had engine light come on. Running rough. Turned out I needed all new spark plugs and had a bad engine coil that I replaced. Runs great and all is well. Then the next day had the P0171 code come up. I cleaned the MAF sensor and put some injector cleaner in the fuel. Cleared the codes. Maybe have around 20 miles on the car after that and the light came back on again.

Do I give it some time for the injector cleaner to work more or something else I should try?

Thanks!
