What Causes Car Jerking?
1 Answers
The reasons for car jerking are: 1. Excessive carbon buildup in the throttle body, fuel injectors, and intake manifold; 2. Poor fuel quality leading to incomplete combustion; 3. Faulty spark plugs or ignition coils causing cylinder misfire; 4. Mismatch between engine torque and transmission oil pressure. The steps to clean the throttle body are: 1. Open the hood and locate the engine's throttle body; 2. Use a flathead screwdriver to remove the air filter and intake pipe, then unplug the electrical connector on the throttle body; 3. After removing the screws, take off the throttle body and use a dry cloth to plug the engine intake to prevent dirt from entering; 4. Spray cleaner on the throttle body and clean it thoroughly.
