• Q: How to clean the fuel injector on 2004 Buick Park Avenue?

  A: The necessary tools for cleaning a Fuel Injector consist of j 37287 (Fuel Line Shut-Off Adapters), j 38500-a (Fuel Injector Cleaner), j 42873-1 (3/8 Fuel Line Shut-Off Adapter), j 42873-2 (5/16 Fuel Line Shut-Off Adapter), j 42964-1 (3/8 Fuel Line Shut-Off Adapter), and j 42964-2 (5/16 Fuel Line Shut-Off Adapter). Gm top-engine cleaner (GM P/N 12346535 for US dealers or Canadian P/N 992872 for Canadian dealers The cleaning solution should be limited to GM Top-Engine Cleaner (GM P/N 12346535 for US dealers and Canadian P/N 992872 for Canadian dealers) for Fuel Injector maintenance. The cleaning agent must never be added to the fuel tank and the concentration should stay under 10 percent. Start the process by obtaining two tanks of j 38500-a then close the bottom valve of the canister. Us dealers need to empty both gm top-engine cleaner measurement containers into j 38500-a while canadian dealers must measure in 48 ml of top-engine cleaner into j 38500-a. The mixture requires 96 ml of top-engine cleaner combined with 864 ml of regular unleaded gasoline when using a different brand. Before use follow the additional instructions to fill the injector cleaning tank with regular unleaded gasoline. Suppressing the Fuel Pump power enables technicians to secure fuel feed and return lines at the Fuel Rail with proper adapters. Join the j 38500-a fuel system to the Fuel Rail before pushing the pressure to 510 kpa (75 psi). Stop the engine after engine stalling then remove the j 38500-a equipment before reinstating the Fuel Pump relay and oil pressure switch connection. After removing the fuel line shut-off adapters you should reconnect the fuel lines before letting the vehicle idle for two more minutes to remove remaining cleaner from the system. Repetition of the injector balance test starting from step 1 requires measurement of fuel pressure drops from each injector to be recorded again. A replacement of the injector with the lowest drop should be made if the highest pressure at the injector exceeds the lowest pressure by more than 15 kpa (2 psi). The technician should pour one ounce of port Fuel Injector cleaner gm p/n 12345104 or canadian p/n 10953467 into each fuel tank gallon recommending additional application during the following refill and educating the customer to repeat this process every 5000 km (3,000 mi) through gm port Fuel Injector cleaner use to avoid further problems. Test drive the car because the customer complaint needs to be fixed successfully.
