What causes a car engine to start spluttering?
Causes for engine splutter 1. Faulty spark plugs 2. Dirty fuel injectors 3. Vacuum leak 4. Dirty mass airflow sensor 5. Exhaust system leaks 6. Faulty catalytic converter 7. Dirty oxygen sensors 8. Worn out seals/gaskets
Why does my car die at stop lights and?
For some vehicles, this issue only happens in cold weather. If that’s the case, then it is best to try and get it fixed during the cold weather season to make sure that the problem is solved. Again, there are many possible causes of this issue.
