Well the spark plug wires weren't the cause of the rough acceleration, as it came back the next day. But I think I found the cause, which would also explain my lean AF ratio, low boost, and low vacuum. An intake manifold leak, gay.

I can see the blue silicone on the intake manifold gasket that it supposed to surround the intake ports. It has been pushed up on two ports (drivers side).

Well at least now I'll get a chance to port match my intake manifold. I've always regret not doing that (I was in a cast when I installed it).
