Engine Light On and Car Won’t Accelerate

Causes

There are a number of possible causes why your engine light might be on and your car won’t accelerate. Some of the most common include:

  • Faulty spark plugs or wires: This can cause the engine to misfire, which can lead to a loss of power and acceleration.
  • Clogged fuel filter: This can restrict the flow of fuel to the engine, which can also lead to a loss of power.
  • Faulty fuel injector: This can cause the engine to run too lean or too rich, which can lead to a loss of power.
  • Vacuum leak: This can cause the engine to run too lean, which can lead to a loss of power.
  • Faulty throttle position sensor: This can cause the engine to run at the wrong speed, which can lead to a loss of power.
  • Faulty mass air flow sensor: This can cause the engine to run too lean or too rich, which can lead to a loss of power.
  • Faulty oxygen sensor: This can cause the engine to run too lean or too rich, which can lead to a loss of power.
  • Faulty catalytic converter: This can cause the engine to run too hot, which can lead to a loss of power.

Symptoms

In addition to the engine light being on, you may also experience the following symptoms if your car won’t accelerate:

  • Hesitation or stumbling when you accelerate
  • Loss of power when you try to accelerate
  • Jerking or shuddering when you accelerate
  • Rough idle
  • Decreased fuel economy

Diagnosis

If you’re experiencing the symptoms listed above, it’s important to have your car diagnosed by a qualified mechanic. The mechanic will be able to use a diagnostic scanner to read the trouble codes stored in the car’s computer. These codes can help the mechanic identify the cause of the problem.

Repair

The repair for a car that won’t accelerate will depend on the cause of the problem. Some common repairs include:

  • Replacing spark plugs or wires
  • Replacing the fuel filter
  • Replacing the fuel injector
  • Fixing a vacuum leak
  • Replacing the throttle position sensor
  • Replacing the mass air flow sensor
  • Replacing the oxygen sensor
  • Replacing the catalytic converter

Prevention

There are a few things you can do to help prevent your car from having problems with acceleration:

  • Keep up with regular maintenance, including oil changes, tune-ups, and fluid checks.
  • Use high-quality gasoline.
  • Avoid driving in extreme weather conditions.
  • Be gentle on your car when you accelerate and brake.

Conclusion

If your engine light is on and your car won’t accelerate, it’s important to have it diagnosed by a qualified mechanic. The mechanic will be able to identify the cause of the problem and recommend the best course of action.
