various hissing/air flow type noises in '88 5kcstq

[auditude at neta.com]

Someone was mentioning noises.  I was wondering if the noises I 
hear when I am driving my 5kcstq are normal.  They seem to come 
from the ECU area, and sound like there is air flowing, perhaps 
relative to engine speed or manifold pressure.

It could very well be the fact that I have no shift boot at all on the 
car, and all kinds of noises eminate from the shifter area.

I just wanted to see if this is something I should be worried about.

Do cars with shifter boots in place exhibit these types of noises?  If 
so, and it's normal, then I won't worry about it.  Otherwise, maybe 
I'll elevate the shifter boot replacement task to isolate it.  I took the 
boot off because the leather had shrunk and would tend to want to 
pull the stick out of certain gears.

Thanks,

Ken
