How do I manually clean the fuel injectors on my car

i have a 1995 acura integra. I ran the tank near empty sevral times and I noticed it running slugish and its even temporarily lost power when starting to accelerate. I have manually cleaned the fuel pump and I also changed the fuel filter but I ran it down around empty again for a few times. the car is sputtering and seems to be losing power at acceleration more often and it kind of seems to be missing but definately slugish sometimes when I accelerate. I ran an addative through it and it has gotten worse since I did.

It's also possible you might have some trash in the fuel tank. If it runs rough after adding fuel, that's the symptom. If it has an in-line fuel filter, check that too.

If you own an older model vehicle (as I do too) you need either a copy of the service manual (not the owner's manual) or a Haynes or Chilton manual for that model. They have step by step procedures for most everything you need to maintain the vehicle and they are available at most auto parts stores.

1 Open the engine compartment, with the engine turned off, and locate your fuel injectors. You might need a guide to help you find this if you are unfamiliar with car engines.
2 Ensure fuel is not pumped into the engine when it is started, by either installing tubing connecting the fuel inlet to the fuel outlet, or by removing the fuel pump and stopping up the fuel return.
3 Hook up a pressurized solvent to the fuel injectors and start the engine.
4 Run the pressurized solvent through the running engine.
5 Shut off the engine and remove the cleaning supplies.
6 Reconnect the fuel lines and fuel pump. Then restart the engine and check for improved performance. If there is no noticeable improvement, run the process again. If this still fails to yield the desired results, you must remove the fuel injectors for off-car cleaning.
7 Take your vehicle to a mechanic. As off-car cleaning requires expensive equipment, it is better to take it to a professional. The service should run anywhere from $30 to $50 and take a little less than an hour.
