The exhaust system is responsible for carrying exhaust gases away from the engine and out of the vehicle. If the exhaust system is damaged or blocked, it can cause the engine to stall because the exhaust gases cannot escape.
Here are some specific ways in which a bad exhaust can cause your car to stall:
- Clogged catalytic converter:
If the catalytic converter is clogged, it can restrict the flow of exhaust gases and cause the engine to stall.
- Exhaust leak:
An exhaust leak can allow exhaust gases to escape before they reach the catalytic converter.
This can cause the engine to stall because the oxygen sensor will not be able to detect the correct amount of oxygen in the exhaust gases and will adjust the air/fuel mixture accordingly, causing the engine to run too rich or too lean.
- Faulty oxygen sensor:
A faulty oxygen sensor can also cause the engine to stall. If the oxygen sensor is not working properly, it will not be able to send the correct signal to the engine control unit (ECU), and the ECU will not be able to adjust the air/fuel mixture accordingly. This can cause the engine to stall.
