3 SIGNS THAT YOUR FUEL INJECTORS CLOGGED / STUCK OPEN OR GOING BAD (AUDI) OR ANY CAR

Summary

In this informative video, Bruce Custom Motors discusses the signs of failing or clogged fuel injectors, which can lead to poor fuel economy and engine issues. He explains the symptoms, such as lean codes, rough starts, oily spark plugs, and black smoke from the tailpipe, indicating a rich fuel mixture. Bruce also suggests using a fuel injector cleaner as a temporary fix, but emphasizes the importance of professional cleaning or replacement for long-term solutions.

Takeaways

• 🛠️ Clogged fuel injectors can be caused by poor fuel quality, debris in the fuel system, or wear and tear.
• 🔍 Signs of a clogged fuel injector include lean codes, rough engine starts, and longer startup times.
• 🔧 If a fuel injector is stuck open, it can cause the engine to run rich, leading to excessive fuel consumption and potential damage to the catalytic converter.
• 💡 Indicators of a stuck-open injector include oily and gassy spark plugs, decreased fuel efficiency, and black smoke from the exhaust.
• 🔌 The solenoid within a fuel injector is powered by a plug and can wear out, leading to issues with fuel regulation.
• 🚗 Poor fuel economy and a decrease in average miles per gallon can be signs that a fuel injector needs maintenance or replacement.
• 🧽 Fuel injector cleaners can provide temporary relief but may not fully resolve the issue.
• 🔄 For a more thorough solution, removing the intake manifold and cleaning or replacing the fuel injectors is recommended.
• 🛑 Worn-out rubber seals in the injector can cause fuel leakage and lead to a lean condition.
• 🛠️ Soaking the injector in acetone can help clean it and improve efficiency, but this is a temporary fix.
• 👍 The video script is a subscriber request and emphasizes the importance of proactive maintenance to prevent fuel injector issues.

Q & A

What are the three main issues Bruce discusses regarding fuel injectors?

Bruce discusses failing fuel injectors, clogged fuel injectors, and fuel injectors that are stuck open.

What can cause a fuel injector to become clogged?

A fuel injector can become clogged due to poor quality fuel, debris in the fuel system, or wear and tear over time.

What are some signs that you have a clogged fuel injector?

Signs of a clogged fuel injector include lean codes, rough starts, and insufficient fuel to match the air intake, causing too much air and not enough fuel.

What does it mean when your car is running lean?

Running lean means there is too much air and not enough fuel in the engine, which can be indicated by lean codes.

What are some symptoms of a fuel injector that is stuck open?

Symptoms of a stuck open fuel injector include fume smells, oily or gassy spark plugs, decreased fuel efficiency, and black smoke coming out of the tailpipe.

How does a stuck open fuel injector affect gas mileage?

A stuck open fuel injector can lead to decreased gas mileage because it causes the car to use more fuel than necessary, making it less efficient.

What does black smoke from the tailpipe indicate?

Black smoke from the tailpipe indicates that the engine is running rich, meaning there is too much fuel being injected and not enough air, causing unburned fuel to exit through the tailpipe.

How can running rich damage the catalytic converter?

Running rich can damage the catalytic converter because the excess fuel and subsequent explosions in the tailpipe generate heat and cause damage, as the fuel is meant to be burned in the combustion chamber.

What are some temporary solutions for a clogged fuel injector?

Temporary solutions for a clogged fuel injector include using fuel injector cleaners available from auto parts stores.

What is the recommended long-term solution for a clogged fuel injector?

The recommended long-term solution for a clogged fuel injector is to remove the intake manifold and clean or replace the fuel injector to ensure it functions properly.
