What causes the check light to blink, a rough idle at times and hesitation in a toyota altis( corolla) 2003 series

SOURCE: 2001 Toyota corolla hesitates on acceleration

Basically this means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust).

SOURCE: Running rough and buzzing at throttle body injectors

Sounds like the engine has a vacuum leak at the throttle body area.

SOURCE: 2000 toyota corolla hesitates when you hit the gas.

i would check your fuel filter and air filter first if they are dirty then i would change them. and if it still does it then it might be one of the sensors on your throtttle body. like your tps sensor or the iac valve or it could be your mas sensor you can also clean these with some throttle body cleaner and mass air flow cleaner that you can pick up at any auto parts store

Are you one of those people who TOP OFF the tank when filling up?

When the EVAP recovery system soak with few ounce of gasoline......the trap vapor will take few days escape.

EVAP system is design to handle fuel vapor. Few ounce of gasoline can damage the fuel vapor recovery relay and decrease the service live of the recovery lines.

=========

You can accelerate the process by locating the charcoal canister (near the nose of the car and same side as your gas filler door)

MOVE the car to outdoor.

Disconnect the EVAP line and let it air out by itself.

DO NOT introduce any heat source or fan to speed up the process.

Reconnect this EVAP hose and use a small amount of starting fluid at the intake manifold.
