1st reset the ecu & check for re-coding before wasting money on un-needed parts. If the light does return check the fuel pressure regulator . . . attach a fuel pressure gauge to the service port then start engine. Check if the fuel pressure rises when disconnecting FPR vacuum hose, if not check hoses & replaces as needed. If hoses are all good replace the FPR. If vacuum is good then test O2 sensor & then possibly replace.
