Are these things supposed to hold a vacuum? My car was running pretty well when I pulled it out but I seem to remember seeing something on how to test.

You can pull a really weak vacuum on it with sucking on it but if the diaphram is cracked then it will seem to hold a vacuum.
Test it with a mittyvac like I said to 15hg to find out. We test them at 15hg cuz thats what you are supposed to pull at idle. It should hold that for 5 minutes without bleeding down. If it does bleed down its got big problems. I have fixed/repaired about 20 of those darn things for 2.0l motors. Geoff |
