Purchacing a Typhoon

[shaggman1]

I have a friend that is looking to purchace a 93 Typhoon. While test driving the truck, it cut out under boost at around 40 mph. Then the check engine light appeared. Under normal driving it was fine, the problem only showed when building boost.
Does anyone know what this could be?

My guess it that it overboosted and the ECM cut fuel to the motor. This is a problem that needs to be attended, most likely the vacuum line are leaking. If the vacuum line are leaking eventualy the wrong line will leak so the ECM won't be able to detect overboost and the motor will grenade. This is a simple fix but can lead ot a big problem if unattended to.
