Often, when a car is jerking when stopped it’s because of a misfire, dirty spark plugs or ignition system problem. A faulty coil pack or the throttle sensor body can also cause problems.
A clogged air filter or fuel injectors can prevent the engine from getting enough air and fuel to run smoothly. In this case, you may need to replace your filter or clean it out with a special cleaner such as catalytic converter cleaner.
Another common reason for a jerk when stopping is an issue with the transmission. Low transmission fluid, a dirty transmission filter or a faulty torque converter can all lead to this problem. In most cases, this is a more serious issue that will require professional diagnosis and repair.
If you have collision insurance, this coverage may cover the cost of the repairs if the jerking was caused by an accident. However, filing a claim can increase your rates in the future. If you don’t have collision insurance, it’s a good idea to talk to your auto insurer about your options. They may be able to recommend a qualified mechanic that can help you fix the problem and get your car back on the road. They may even be able to tell you whether or not you have to pay your deductible before they will cover the repairs. This can save you a lot of time and hassle.
