5000 CSQT engine bogs under hard acceleration

[Kneale Brownson]

Look through and follow the boost-related items

The Michelin Man hose between the intercooler and the intake casting that 
says turbo on it (the hose with the wire in its grooves) most likely has a 
slit beneath the wire in one of the grooves on the backside of it.  The 
test for a failed MM hose is to remove it from the car, hold the ends in 
your palms and pump it like an accordian.  You'll know real soon whether it 
holds pressure.

The black plastic duct actually works the other way:  It brings air from a 
fan to the injectors to help cool them when the engine is shut 
down.  Supposedly prevents fuel percolation and vapor lock.
