Let’s find out…

5. BMW Engine Sputtering? Here’s Why

6. Fuel injector is likely dirty

7. Yup… a dirty fuel injector can
cause a car engine to sputter.

8. That’s because a dirty injector limits
the fuel supply into the combustion
chamber.

9. Carbon fouling of
spark plug

10. Engine sputtering in cars is almost
always caused by carbon-fouled spark
plugs.

11. You should therefore clean
your spark plug tips regularly.

12. Defective sensors

13. Faulty sensors make it difficult
for the ECU to control engine
operation.
• The engine may sputter
because of this.

14. Check the condition of the various sensors in
your car to see if they are working fine.

15. Damaged engine seal or
gasket

16. Your BMW engine may also sputter due to
a worn engine gasket or seal.

17. Replace the defective seal/gasket
before things take a turn for the worse.

18. Issue with the exhaust
system

19. It is possible to experience engine sputtering if
the catalytic converter or other key components
of the exhaust system malfunction.

20. To Sum Up…

21. If your BMW engine is sputtering, don’t
take it for granted.

22. Take the help of a trusted professional
to resolve the issue.
