While driving on highway my Honda Accord started shaking badly and check engine light came on. I slowed down and moved my car on side. I switched off. When I restarted the car it wasnt accelerating beyond 20 kms/hr. I called an mechanic who opened the bonet to see the engine. The engine was shaking badly and he opened to see the spark plug. He replaced the spark plug, but it didnt work and engine light stayed on. Later he replaced ignition cord. This increased the maximum speed to 40 km/hr and thr car doesnt go beyond this. The check engine light keeps on coming and going. And tge VSA light has also come on with the yellow triangle of ! Sign. I wonder as to what is wrong with the car.

The "check engine" light is an indicator for a system that monitors many electronic functions in the system, also called the "malfunction indicator lamp" (MIL). It can come on for any of hundreds of different causes from any of the systems that the computer monitors. Some are very important and can lead to further component or engine damage and some are emissions related not as serious but still a problem and need to be repaired.

Your first step is to have the computer scanned to retrieve the trouble codes that were set when the check engine light came on. Those codes will give you specific information about what the computer saw and will get you pointed in the right direction to find your problem.
