The o2 sensor,s controls fuel and air to your car,the o2 sensor,s tell the ECM/brain what mixture of fuel to send to engine,right now the ECM is not getting a true reading on gas flow,and puts your car in what is called a limp mode,you will have to have it repaired before it will run correctly.


Thank you. But what would have to be replaced the ECM?
