Isx surging or rough idle

I can assure you sea foam isnt gonna destroy the engine. Its made for both gas and diesel. I personally would much rather spend 10 bucks on an injector cleaner than spend hrs tearing down actuators, cleaning the mounting surfaces and replacing them steel seals. Especially if there wasnt a thing wrong with em. If cleaner dont work then move on to actuators and injectors.
