•Remove top and regulator assembly from top of fuel injector cleaner.
•Fill the container with one bottle of D-Karbonizer.
•Install top and regulator assembly again.
•Connect the canister hose to a decarbonizing adapter.
•Locate a manifold vacuum port (NOT ported vacuum) near the throttle body or carburetor. (This will distribute the decarbonizing solution more evenly.)
•Connect the decarbonizer hose (with adapter) to the manifold vacuum port.
•Start the engine.
•Manually increase throttle to 1,500 RPM while slowly opening the shut-off valve. (The engine wi11 run rough and RPM will decrease.
•DO NOT manually increase RPM.) When the container is empty, turn the engine OFF.
•Remove the adapter fitting from the engine.
•Connect the vacuum hose.
•Let the vehicle sit for at least 30 minutes to allow solution to work on soft carbon deposits.
•Test drive the vehicle for at least 15 miles to flush loosened carbon deposits out of the system.
