In my search for a lowish boost Kr problem, I decided to make sure I have no big vacuum leaks.
I 've been replacing all the vacuum hoses and using a Mityvac to test for leaks. I was surprised that hooking the Mityvac to a short piece of hose, then to the vacuum nipple on my Bosch adjustable fuel pressure regulator, it didn't hold vacuum well at all. The needle moved when I applied vacuum but sank back to zero within a second or so. Is this normal?
Also the EGR solenoid. Applying vacuum to the larger hose that goes into the solenoid, it leaked audibly. Car was off at the time. Is this normal? It sounds like it's an open system which of course doesn't sound right. Perhaps it's a closed system when power is applied? Also does anyone know if you can get the little tiny air filter that goes under the round plastic cap on the solenoid? I somehow put my stupid finger into mine tearing it a bit.
Thanks
