their are so many issues when it comes to rough running. Plugs, fuel, CO, wiring. you will have to go from one end to the other. start with plugs/leads, then fuel line/filter and pump, then start checking sensors, a stuck sensor can make or break you.

Sound like a bad throttle position sensor or TPS.

Code P0111 refers to the air temperature sensor which is part of the mass air flow sensor located in the intake ducting. It is held in by 2 screws and has a 5 wire terminal connector.

The brake lights work regardless of the ignition switch. There is normally a switch mounted under the dashboard, that presses against the brake pedal hangar. Normally, when you press the brake pedal, this switch loses contact with the hangar, and the brake lights come on. If the switch gets broken or out of adjustment, the brake lights can stay on at all times. This will eventually kill the battery. Readjust or replace the brake light switch.

Try testing battery to see if it is still good. If so might be a short in writing for ground or starter could be going bad. If not any of these issues please let me know. Good luck. Short to ground could cause your symptoms but a short to ground is easily fixed.

Your car is probably fitted with an immobiliser , you need to have the original key in the car when you start it or replace the immobiliser module and key with a programmed chip to match that immobiliser , otherwise go to the dealer with VIN number and they will replace the key (not cheap usually) the trick is the immobiliser chip in the key must match the one in the car , it's a security feature .
