Inspection 2; To check this, you’ll need to have a stethoscope—. Put the stethoscope against the hose and listen for signs of air leakage.

It’s pretty small, around the size of a clothespin, so keep your eyes open for this component. (By the way, the oxygen sensor is a small device that’s used to measure the amount of oxygen in your exhaust emissions. The moment there is too much or too little oxygen in your air-fuel mix, the oxygen sensor sends signs to your engine computer to lessen or increase the flow of fuel—whichever applies.)
