Problem (5kcstq)

[Andrew Shea <anshea@anselm.edu>]

Here goes,

	The car is an 87 5000cstq, 110,000miles, Charlie Smith Spring 
(one shim), K&N, and the cam timing has been advanced 1 tooth.
	Here is the problem...  Under full acceleration and around 3500 
rpm or above the car hesitates/bucks (ever so slightly).  I watched my 
mechanical boost gauge and it seemed as if the boost was waving between 
8psi and 10psi during the hesitation.
	Intercooler hose?  Plugs (had something like this happen with my 
66 Mustang)?  Does anyone have any ideas?

	Thank you guy,

	Andrew
