Vacuum issue?

["Ed Garbade" <edgarbade@xxxx>]

Noticed my car performs OK in low gear but bucks as I move up in RPM and 
gears (this started a couple weeks ago when I changed the antifreeze). I 
initially was thinking it was the transmission slipping but the more I drove 
it the more it felt like the engine was missing on an irregular basis. This 
symptom is making me lean toward a vacuum leak.

That in mind, I am looking for a list showing all vacuum lines, connectors, 
locations, and part numbers/sizes on our car. In addition to the lines, I 
would be interested in your thoughts of what other components are potential 
gremlins I should examine?

I know I can use the vacuum routing label and section 7.3.0 of the manual 
for some of the highlights but was wondering if anything existed as a 
checklist without going to tracing individual lines and/or extracting 
numerous pages from the manual. I don't mind doing this if needed (and will 
be happy to document if this is the route I have to take); however, I would 
prefer not to re-invent the wheel if it already exists.

As a side bar, my car was running fine until I flushed the coolant system 
(because I had replaced most of the hoses). During the flush I did spill 
some antifreeze on the engine. After this my water pump and idler pulleys 
started making noise so I sprayed them with a penetrating lubricant (P B 
Blaster). This seemed to stop the noise (it has been driven about 50 
miles).

Looked through the archives and didn't see anything along this line.

Thanks,
Ed
