I have a 2005 Toyota Celica GTS, 175,000 miles, 6 speed manual transmission. Getting two codes P0420 & P0441. It wants to stall at idle just after filling up gas tank. If just siting parked I have to give it gas to make it not stall. Once I drive a mile or two down the road it's fine. Every once in a blue moon when I push the clutch in coming to a stop it will stall. Any idea what the issue is? Thanks!
Most likely an evap system problem.
bad fuel pump or EVAP failure
When you get gas, when filling and it clicks off, do you keep trying to get all you can get in it, or quit when it stops the first time?
I quit when it clicks and hang up the pump.
