I haven't tried this on my e46 yet, but I used to use starter fluid to check for vacuum leaks. Spray it in the general area, and the engine rpm will increase when a leak sucks in the fluid. You can then isolate the leak by narrowing in on the area, using shorter bursts of spray in more localized areas. With the computerized engine management system used in the E46, does this still work?
