Could be an air leak somewhere

 

sorry i might seem rewally thik but what do u mean by the co needs cheking first?

 

The mixture, basically what comes out of the exhaust, needs checking to see if running lean, an air leak can also upset the car, but more likely to do all the time.
You are not thick, a thick person would not ask, the air and fuel need to be in precise ratio's to each other, this is what determines the end result of the burnt gasses CO, or carbon monoxide output.
