Open the engine compartment, with the engine turned off, and locate your fuel injectors.
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.
Hook up a pressurized solvent to the fuel injectors and start the engine.
Run the pressurized solvent through the running engine.
Shut off the engine and remove the cleaning supplies.
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.
Off-car cleaning requires expensive equipment that most people don't own in their home shops. 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.
