Answer
Salman, is there any check engine codes being triggered? If so, evaluate and diagnose these codes first and this will guide you in your next direction for service. You need an OBD-2 code reader/scanner. If you do not have one a local auto mechanic could perform this service very quickly and at a minimal expense.
