The Most Common Car Repair Mistake and How to Avoid It

Firing the parts cannon is a common car repair mistake that can cost you time, money, and effort. It can also cause more problems for your car and yourself.

Car repairs can be a daunting and expensive task for many car owners. Whether you are a DIY enthusiast or a professional mechanic, you want to make sure that you fix your car problems correctly and efficiently. However, there is one common car repair mistake that can waste your time, money, and effort: firing the parts cannon.

What Is Firing the Parts Cannon?

Firing the parts cannon is a term that describes the practice of throwing parts at the problem without doing any diagnostics. This means that instead of finding out the root cause of the problem, you just replace parts based on assumptions, guesses, or recommendations from the internet or other sources.

For example, if your car has a check engine light on, you might use a code reader to get a diagnostic trouble code (DTC). However, a DTC does not tell you exactly what part is bad or what is causing the problem. It only tells you what system or circuit is malfunctioning. A DTC can have multiple possible causes and solutions, and some of them may not even involve replacing any parts.

If you fire the parts cannon and replace a part based on the DTC without performing any tests or checks, you might end up wasting money on a part that you did not need, or worse, creating more problems for your car. For instance, if you replace an oxygen sensor based on a DTC without checking the wiring, connectors, or vacuum leaks, you might damage the new sensor or cause other issues with the fuel system.

Why Is Firing the Parts Cannon a Bad Idea?

Firing the parts cannon is a bad idea for several reasons:

• - It is costly: Replacing parts without knowing if they are faulty or not can rack up your repair bill quickly. You might end up buying parts that are expensive, unnecessary, or incompatible with your car. You might also have to pay for labor costs if you hire a mechanic to do the job for you.
• - It is ineffective: Replacing parts without fixing the underlying problem can leave your car in the same or worse condition than before. You might not solve the original problem, or you might create new problems by installing faulty or wrong parts. You might also void your warranty or damage other components of your car.
• - It is risky: Replacing parts without proper diagnosis can be dangerous for your car and yourself. You might install parts that are not suitable for your car model, make, or year. You might also install parts that are defective, counterfeit, or recalled. You might also expose yourself to electrical shocks, burns, or injuries by working on your car without proper tools or safety precautions.
