Hey Steve, how do you know if you have an exhaust leak?

@@prestonharrison8764 You can usually tell by a muffled sound after the engine, and before the tail pipe, another way I use is paper or anything that's easily flexible and put it around the exhaust pipe as the engine runs, as you'll feel the exhaust gas blowing on the paper or whatever you used to detect the leak.

I have a po156 code popping up in my 2003 Ford F-150 , do I need to change the oxygen sensor?

Hi! I got the p0156 on my bmw e46. The scanner says "D8 Signal, ox.sensor after cat. conv., bank 2, no signal". Does that mean that there is no signal from the sensor?

Привет! Большое спасибо за видео. У меня bank 2 sensor 1 показывает 0,7 V, а bank 2 sensor 2 показывает 0,2V. Неисправность катализатора или могут быть еще причины?

Здравствуйте, подтвердите, если это единственный код, который вы получаете.
