I have a 2002 Mercury 4 stroke EFI motor. It seems to run fine when I run at low speeds but as soon as try to open it up it bogs down. I then back down on the trottle and it seems fine again. I took it to a marine dealer and they said it was clogged injectors and they recomended me running injector (Mercury Quickleen) cleaner throught a tank full of gas. They said if that does not work I should have the 4 injectors cleaned for $500.00. Any suggestions? Will the injector cleaner work? Could I clean the injectors myself? I used to be an auto mechanic. Are there other things I should check before sending them in?

Thank you, Todd
