Causes Of Engine Misfires


Engine misfires and stalling are common issues with the 2012 Honda Civic. These problems can arise due to various factors, such as ignition system malfunction, fuel delivery issues, and vacuum leaks. Ignition system malfunction can disrupt the spark plug firing sequence, leading to misfires. Fuel delivery issues, on the other hand, can result in a lean or rich air-fuel mixture, affecting the engine’s performance. Vacuum leaks can cause a disruption in the air intake, negatively impacting combustion.

These engine problems don’t just affect the car’s performance, but also pose safety risks. Misfires can cause the engine to stall, leading to loss of power and control while driving. To address these issues, several repair options are available, depending on the root cause of the problem. The costs of repairs can vary, depending on the severity of the issue and the specific components that need to be repaired or replaced.


Repair options and costs

Repair Option Cost Range
Ignition system repair $200 – $600
Fuel delivery system repair $300 – $800
Vacuum leak detection and repair $100 – $400

2. Faulty Oxygen Sensors

The 2012 Honda Civic is a car model that car buyers should avoid due to several reasons. One of the major issues with this vehicle is faulty oxygen sensors. Oxygen sensors play a crucial role in the engine by measuring the amount of oxygen in the exhaust gases to optimize fuel efficiency.

A failing oxygen sensor can cause various symptoms that indicate there is a problem. These include decreased fuel efficiency, as the engine may run too rich or too lean without proper oxygen level measurements. Another indicator is the activation of the check engine light, which serves as a warning for potential issues.

Ignoring the faulty oxygen sensors can have long-term effects on the engine and emissions. The engine’s performance may be compromised, resulting in reduced power and increased emissions. Over time, this can lead to more serious and costly engine problems.

Replacing oxygen sensors is necessary to restore the car’s performance and ensure it meets emission standards. However, the associated costs may vary depending on the specific make and model of the car. It is important to address oxygen sensor issues promptly to avoid further damage to the engine and costly repairs.

3. Transmission Problems

Transmission problems are one of the main reasons why you should avoid the 2012 Honda Civic. This model is known for experiencing various issues with its transmission system.

Some of the common transmission problems found in the 2012 Honda Civic include shifting delays or difficulty, transmission slipping, and overheating. These issues can be frustrating and may impact the overall performance of the vehicle.

Shifting delays or difficulty can make it challenging to change gears smoothly, resulting in a less enjoyable driving experience. Transmission slipping occurs when the transmission fails to engage properly, causing a loss of power and acceleration. Overheating can lead to serious damage to the transmission system and even engine failure.

The potential causes of these problems can vary. They may be due to manufacturing defects, wear and tear over time, or inadequate maintenance. If left unaddressed, these transmission issues can lead to costly repairs or even complete transmission failure.

When confronted with transmission problems in the 2012 Honda Civic, there are repair and replacement options available. It is essential to consult a professional mechanic or transmission specialist to diagnose the specific issue and determine the best course of action.

In conclusion, transmission problems are a significant concern when considering the purchase of a 2012 Honda Civic. Being aware of these issues and taking proactive measures can help avoid potential headaches and expenses down the road.


Considering the various drawbacks, it is advised to avoid purchasing a 2012 Honda Civic. Its recurring transmission issues, lackluster fuel economy, and outdated interior design make it a less desirable option. Instead, consumers are urged to explore newer models that offer better reliability, improved performance, and enhanced features.

By making an informed decision, car buyers can ensure a more satisfying and enjoyable driving experience.
