2003 TC has rough idle when purge valve is connected (No SES light). Idles fine when disconnected. Have changed purge valve, vent valve solenoid and canister. When fueling the tank, gas pump shuts of almost immediately as if were full. What are the consequences of leaving purge valve disconnected? Can "topping off" at the fuel pump damage vent valve? Have not performed a smoke test to check for leaks. Can the fuel tank pressure sensor cause this problem? Any help is greatly appreciated. Thank You in advance.
