The dealership did a spark plugs replacement, oil change, and state inspection. The engine malfunction light came on immediately afterwards. They found it was a disconnected item in the fuel system and connected it. The malfunction light still came back. Now they are saying that I have the P1457 code and need to replace EVAP Bypass Solenoid Vave and the canister.
I am wondering if the damage to the Evap system was due to their mistake of leaving an item in the fuel system disconnected.
