UPDATE--Vac Leak-type44 QT---

[HOUSTON]

Previous Posting

Can anyone tell me where the most common vac-leaks are on this car? I
replaced the O2 sensor, valve cover gasket (rubber type), T-shaped hose
atop the valve cover, fixed the air intake wiring(F/C 2322), and cleaned
the ISV, yet I still only get a 1.1 boost reading. I have not replace
the Cat. Conv. yet, but that's next. Is there anything else that can
give a low boost reading? There must be a leak somewhere. Please, any
help is much appreciated.

Well, I've replaced several small vac hoses, but to no avail I still get
1.1 and still hear a loud whistle from under the engine when traveling
under overpasses.  The whistling doesn't change pitch with speed. I took
off the M-M hose, and it's fine.  Although, I did find a small slit @
the end of one of the ISV hoses, next to the metal clamp.  I'll replace
that tomorrow, along with the Throttle Switch, Injector Cooling Fan
Sensor, and Multi-Function Temp Sensor.  If anything changes tomorrow,
I'll post.  Thanks for all the helpful email.
