So the canister thing on the back right of the engine, I believe it's called the vacuum amplifier. Since I'm not using the lean-burn computer anymore, it it really necessary to keep it in there, or can I take it out? I just don't really know what purpose it serves, and I have to take it out anyway to get access to the oil pressure sensor that I need to replace. I'd like to clean up some of the junk from under there. I'll try to get up pictures tomorrow so y'all will know what I'm talking about.
