Hello Amordok, I tell you something you left to do or perform and did not take into account whether, when you repaired the engine you had to have reviewed the catalyst in case it was covered or damaged inside, as well as the pressure of the gasoline pump, and depending on the mileage that the car brings to me to tell you that you solved a problem and caused another less notorious, but more important than the lack of power, I will tell you, I will of the exhaust system, you stop having a monitor of the oxygen sensors and stop sending a signal to the comp, so it causes a richer combustion ratio to be maintained, so you will have a greater consumption of gasoline and do not pass the verification if they verify it or pass it from the The same catalyst and we do not damage the environment and oneself or it would not be better. I want us to be more aware of the medium where we live if, in case we are up to the carbon dioxide neck and we are killing ourselves with lung cancer or where the virus is staying. Reflect and reflect your customers. Greetings from Mexico D, f.
