My car has a manual transmission.

Hello, thank you for writing in. The check engine light illuminates when the vehicle’s computer runs tests and detects and issue. The vehicle is constantly running tests on every system in the vehicle. Therefore it is hard to determine which system the warning light may be related to. The first thing to do is read the codes which must be done with a scanner. Use the codes that are pulled to help direct you towards looking into certain components. With that being said, considering your symptoms, you are likely looking at a fuel, air, or spark issue. If the codes do not help, start testing for spark, fuel, pressure, and looking into the air intake further. For more help resolving the issue, contact our service department to schedule an appointment.
