6. Check the oxygen sensor for any damage and replace it if it is faulty. Sometimes the cleaning of the sensor solves the problem.

7. Have look at the spark plugs. It may have got a lot of carbon deposits or it may have a disconnection from its cable. Get it cleaned properly. If the spark plug is worn, then it would always remain faulty, you have to remove it and install new plug.

8. The catalytic converter is checked well, if it is clogged, then it is cleaned well or even replacement can be needed.

9. Check the air intake system, there can be some vacuum leaks or faulty MAF sensor. Fixing the leakage and the replacement of MAF sensor is done.
