The explorer experienced severe exhaust pipe shaking when starting up during use. There are basically the following reasons:
Question 1: Exhaust pipe shaking with high idling speed during cold start.
Solution: When the cold car is started, the engine has not reached the best working condition. The high engine speed and large jitter will also drive the jitter of the entire car, so the exhaust pipe jitter occurs. Just wait a moment. It is normal for the jitter to fade from one minute to two minutes.
Question 2: The exhaust pipe is fixed.
Solution: You need to raise the car, check the fixing problem of the exhaust pipe, whether the lifting lugs are fixed, or if they are loose, it will shake badly if there is a little vibration. You can fix it again and collect it from the auto repair shop. Labor cost of 50~80 yuan.
Question 3: The engine produces knock .
Solution: If the engine is working, the knock caused by the mixture is too thick/lean will also cause abnormal vibration of the whole body, and the exhaust pipe will also shake too much if the exhaust pipe is soft. You need to check the engine The cause of the knock. For example, severe carbon deposits on the throttle, failure of intake pressure sensor , poor fuel quality, dripping of fuel injectors, blockage of air filter , etc., you need to use a diagnostic computer to access the data stream to check step by step.
The exhaust pipes of most models have a slight jitter,It’s just that many models are hidden in the rear bumper, so you can’t see the vibration of the exhaust pipe. Unlike this car, which is directly exposed, some car owners are concerned.
The above is the solution to the severe vibration of the exhaust pipe when starting up, for reference by netizens.
