The check engine light comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.
This happens when there is an Active Misfire, or a urgent pending service matter. Get your codes checked.
The service engine soon light comes on when the engine computer has detected a malfunction and set a code. You need to have the system checked for codes to know possible causes.
There is a problem with the emissions system.
Check your sensors.
It is an engine misfire. Don't accelerate too fast or brake too fast. Get your car into the shop as soon as you can because it can/will cause damage to your catalytic converter.
