What is the most effective way to check for vaccum leaks? As far as I can see all hoses under my engine bay are connected and I've never removed any hoses aside from my intake since I've had the car (almost 7 years now). I looked inside my intake manifold and there seems to be some soot inside there. Is that normal? If not how the heck to I get that out?

My car ran better on 93 than 87 when it was bone stock. I use 93 now. If I were to purchase 87 in my next fuel-up; the car will run like ****.

My timing is not advanced but when I put in 87 the car runs horrible. It feels really sluggish and I will almost definitely get a CEL if I get on it for a lean condition. With the 93 I get no check engine lights and the car idles a lot better. The difference is only a few bucks per tank so I just use the 93.
