Hello, i have a problem with my car, when i put gas and fill the tank above the middle, it starts to smell strongly of gas and it makes stops during moving. And also when i stop at traffic lights it turn off. I went to toyota cyprus and they charged the cap on the tank and valve the gives gas, i also changed the fuel master ( i think) and nothing changed! Now i have also the engine check light and show catalytic code. Can anyone help me?

Hi Irini,a strong gas smell as you say could be due to a fuel leak in the lines, tank, or filler neck. Fuel leaks are dangerous, so I would get this checked ASAP. It could also be related to the EVAP system, which controls fuel vapors. A faulty purge valve, vent valve, or charcoal canister  can cause a fuel smell, especially when the tank is higher.

The stalling and check engine light along with a catalytic converter code indicate a problem with the air fuel mixture. This could be caused by a bad fuel injector, a clogged air filter, or a malfunctioning MAF sensor. A check engine light with a catalytic converter code might also point to a failing catalytic converter or faulty oxygen sensors.

I would avoid filling the tank past the automatic shut-off, as this can overwhelm the EVAP system. Take your car back to Toyota Cyprus and explain the issues, stalling, check engine light etc,and tell them about the catalytic code. They should run a more detailed check. If you don't get any resolution try an independent garage they may offer a fresh perspective and locate the exact cause. Remember that if you keep your fuel filter clean and replace the air filter on a regularly basis can help prevent the stalling issues.

I hope this helps.
