It should be done around 30,000 miles when the fuel filter needs to be changed.

How do I remove and clean a fuel injector?


You have to remove the fuel rail from the engine. Then you can pull out all of the fuel injectors to clean them. Most tune-up shops offer a fuel injection cleaning service that doesn't require removal of the injectors. If your car has high mileage, you can get some extremely good deals on brand new injectors from an on-line retailer, like Amazon.

yes that is possible ..you forgot to replace the fuel filter or clean it ,,,this is simply a fuel filter problem ..I know what you are saying about the injection system ..it will also help to put a half of a can of Sea Foam in your gas to clean all carbon from the Intake system ..you will look like you are having a BBQ for 30 minutes or less from the trash burning out of your engines exhaust also you will get better gas mileage and run really smooth

Hi


As far as the review says the mileage should not falter since it is new as you said. However

These are the causes of a poor mileage in a car:-


Poorly Inflated Car Tires

Car tires that are improperly inflated create significant road resistance and drag on a moving car. A car engine has to work harder to propel a car forward due to this increased tire/road resistance. This resistance chips away at a car's gas mileage.


Dirty Air Filter

A dirty air filter impedes air flow into a car's engine, a process that disrupts normal engine combustion and makes it less efficient. This causes a reduction in both engine performance and gas mileage.


Bad Spark Plugs

Spark plugs are responsible for igniting a car's air/fuel mixture, an event that causes a mini explosion inside a car's engine cylinders. Bad or dysfunctional spark plugs don't fire, or ignite, properly; thus, they affect engine combustion negatively, which in turn negatively affects gas mileage.


Bad Oxygen Sensors

For a car to be at its most fuel efficient, its oxygen sensors, small and electronically operated, automatically adjust a car's air/fuel mixture and have to be functioning properly. Bad oxygen sensors cause abnormal air/fuel mixture ratios, a condition that results in poor gas mileage and poor vehicle performance.


Leaky Fuel Injectors

A car's fuel injection system is responsible for injecting precise amounts of fuel into a car's engine cylinders, where it is combined with air and ignited. For a car to perform properly, a specific amount of fuel has to be injected by each fuel injector into each engine cylinder. A leaky fuel injector wastes fuel by leaking it outside the engine and reducing the amount of fuel that makes it into the engine. This results in wasted fuel and reduced gas mileage.
It is suggested to start with a code scanner to find out if there are any stored fault codes in your car.

Poor gas milage


Poor gas mileage can have many roots but the best way is always to start with the ignition system. Have a look at the sparkplugs, if you've got the I6 4.0 engine it is easy to check them. Spark plugs are cheap and easy to replace. Also check the spark plug wires, be sure the connections are tight and free from rust. Check the distributor cap and rotor and if they are rusty/greasy clean them up. After you've cleaned and checked the ignition items (spark plugs, wires, distributor cap and rotor) you can move on to the fuel injection system.
Replace the air filter, it is cheap and most people overlook that single item.

When was the last time you replaced the fuel filter? A clogged fuel filter reduces power drastically which in turn affects fuel mileage.

2002 Yukon fuel injection service needed?


General Motors does not have a service interval for fuel injectors, though they make a injection cleaner if there is a drivability issue. Other companies suggest a injection cleaning interval of 48000 miles. I would suggest an in tank additive from a reputable company every couple of years.

Car feels like it wants to shut off


I am fairly certain it is the idle air control valve, you did not mention your mileage but idle air control valves typically wear out at about 100,000 miles to 150,000 miles.

Location of the PVC and gas filter on 4 cylinder 2003 Solara


The PCV and the fuel filter replacements are not going to increase you fuel mileage. What you should really consider is getting some good fuel injection cleaner into the tank, and get an "induction system cleaning". Those two items alone will address most of your mileage issues. The PCV does nothing for mileage, nor does the fuel filter. Also, for maximum fuel mileage, you should have the correct sparkplugs from Toyota in your car. "Aftermarket" plugs doe not perform very well at all.
