Takeaways
- đ ïž Clogged fuel injectors can be caused by poor fuel quality, debris in the fuel system, or wear and tear.
- đ Signs of a clogged fuel injector include lean codes, rough engine starts, and longer startup times.
- đ§ 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.
- đĄ Indicators of a stuck-open injector include oily and gassy spark plugs, decreased fuel efficiency, and black smoke from the exhaust.
- đ The solenoid within a fuel injector is powered by a plug and can wear out, leading to issues with fuel regulation.
- đ Poor fuel economy and a decrease in average miles per gallon can be signs that a fuel injector needs maintenance or replacement.
- đ§œ Fuel injector cleaners can provide temporary relief but may not fully resolve the issue.
- đ For a more thorough solution, removing the intake manifold and cleaning or replacing the fuel injectors is recommended.
- đ Worn-out rubber seals in the injector can cause fuel leakage and lead to a lean condition.

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.
