Check the ignition leads and the engine coolant temp sensor which tells the ecu how much fuel is needed .

I have noticed there's some wiring at the back right of the engine bay that are not connected i think might be related to the wiring from the temp sensor, why would the disconnect the wiring? got the car about a week ago so finding new crap out lol
