  • The engine hesitates to start or does not start at all.
  • Lower power delivery 
  • Poor exhaust
  • Rough Idling
  • Excessive consumption of fuel

6. Dirty Spark Plug Problem

Dirty Spark Plug Problem

The spark plugs can visibly affect the functioning of engines. This problem arises due to the deposition of pollutants on the spark plugs and intensive corrosion. The problem can lead to ford explorer sputtering while accelerating and four other symptoms that assist in confirmation are as follows:

  • Engine hesitant while performing
  • Lack of acceleration 
  • High consumption of fuel and low efficiency
  • Engine often surges and misfires

7. Airflow Sensor Fault

Airflow Sensor Fault

The problem of MAS (Mass Airflow Sensor) can cause many drivability problems in an automobile. One such issue is sputtering noise while trying to accelerate. Many other symptoms signify the malfunctioning of the airflow sensor problem. The symptoms are mainly related to the engine. Here are all of the rest symptoms: 

  • Engine problems: Stalls, hesitates to respond, hard to turn over, and portrays engine hiccups
  • Extra-lean and rich idling takes place
  • There occur many other drivability issues

8. Vacuum Leak

Vacuum Leak

The vacuum can occur due to broken seals and sheaths. The problem rarely causes sputtering. However, it is significantly one of the reasons for sputtering. Many other symptoms can confirm the issue when it assists the sputtering problem during the inspection. Here are the other symptoms:

  • Regular idling problem
  • Engine hesitation
  • Vacuum sounds
  • Engine light warning
