Will Sea Foam unstick a stuck open fuel injector? [SOLVED] Asked by John Y. In Tennessee Will Sea Foam Motor Treatment unstick a stuck open fuel injector?
If dirt, gum, or varnish residues are causing the fuel injector to stick open, then yes. Sea Foam in a strong concentration will help clean that fuel injector and help it work properly again. Don’t be afraid to use a full can of Sea Foam (or two) in a low amount of fuel (1-2 gallons). High Mileage would be a really great choice as it’s made for tough residues.
