How to Diagnose Car Jerking and Engine Light Problems

If your car is jerking and the engine light is on, there are a few things you can do to diagnose the problem:

• Check the engine code. The engine code is a five-digit code that is stored in the car’s computer. This code can help you to identify the specific cause of the problem.
• Inspect the spark plugs. The spark plugs are responsible for igniting the air-fuel mixture in the engine. If the spark plugs are worn or damaged, they can cause car jerking and engine light problems.
• Check the fuel filter. The fuel filter removes impurities from the fuel. If the fuel filter is clogged, it can restrict the flow of fuel to the engine, which can cause car jerking and engine light problems.
• Inspect the air filter. The air filter removes impurities from the air that is drawn into the engine. If the air filter is clogged, it can restrict the flow of air to the engine, which can cause car jerking and engine light problems.
• Check the transmission fluid. The transmission fluid lubricates the transmission components. If the transmission fluid is low or dirty, it can cause transmission problems, which can lead to car jerking and engine light problems.
