Engine hesitates during acceleration Inspection

What does Engine hesitates during acceleration entail

A top-rated mobile mechanic will come to your home or office to determine the reason why your vehicle is hesitating while accelerating. The mechanic will then provide a detailed inspection report outlining the nature of the hesitation and the cost of any repairs that need to be made.

Keep in mind

  • Because hesitation while acceleration is a symptom of many potential problems, it can be helpful to identify other sensations you may be noticing form your vehicle. For example, a vehicle that not only hesitates, but surges at times, may have a bad mass airflow sensor. By noticing other issues with the vehicle while driving, and giving that information to the mechanic, you may help him or her better identify the problem.

How it's done

  • A mechanic will first plug into your vehicle’s computer using a code reader/scanner to better identify what the exact issue is. In addition to reading trouble codes, he or she should also be able to get readings of oxygen/fuel intake to make sure those numbers are where they should be. Once the mechanic gets this information they can begin to fix any potential issues. If the mechanic believes that the mass airflow sensor has gone bad or is failing, he or she will first examine the sensor for any superficial damage. The mechanic will also ensure that the sensor is wired correctly and that no damage has been done to the wire harness. The mechanic should then remove the mass airflow sensor and replace it with a new one if necessary. If the mechanic believes the problem is the fuel pump, he or she will remove the fuel tank if necessary to inspect the pump. If the pump has indeed failed, the mechanic will replace it. If the fuel tank itself it beginning to show signs of age, it may be convenient to change the pump and tank at the same time. If the mechanic suspects the throttle position sensor, he or she will test the throttle position sensor and it’s wiring to see if it is functioning properly. If it is not, the mechanic will remove the throttle positioning sensor and the wiring and replace them. In between removing the old sensor and replacing the new one, the mechanic should take the opportunity to clean the throttle body. The mechanic will then ensure the new throttle positioning sensor is working properly and transmitting the correct information to the vehicle’s computer. If the mechanic believe the problem is dirty or failing fuel injectors, he or she will inspect the injectors to check for any signs of damage or leakage. The mechanic should also take this opportunity to replace the fuel filter if it is not a part of the fuel pump. They will then replace the injectors and test them to make sure they are functioning properly. In all cases, the mechanic will start the vehicle to make sure that all of the new components are working properly. In the event that an issue has caused a warning light to come on, the mechanic will be able to clear the trouble code associated with the light using a reader/scanner.
