Hi,my name is mike and I will assist you with your question.
How many miles are on the vehicle?
Customer: replied 3 years ago.

the car runs well most of the time occasionally when stopped at lights etc. the engine runs poorly and not enough revs to pull away so stalls. i then restart the engine which struggles for a few minutes before it builds up enough revs and pulls away. when the engine runs poorly loads of smoke is omitted from the exhaust. the car as done 114.000miles and is seviced regularly. hope that helps Bob Plumpton

Expert:  Mike Kelly replied 3 years ago.
Ok from what you are describing the vehicle has a fuel injector that is failing and allowing one of the cylinders to not be primed correctly. This turns on the light and results in the symptoms and the smoke that you are getting. The fuel injectors needs to be tested as a first step and this is best done with a cylinder balance test which shows which one is failing.
