I use to be able to lock and unlock all the doors, trunk lid and fuel door, on average about 5 to 8 times after the engine has been turned off. I am now down to about 2 times due premature loss of vacuum.

I will be replacing soon the leaking Shutoff valve at IP (evidence of oil in the vacuum line, luckily captured by the pre-filter I installed like Thomaspin) and I’m wondering if the two are related or coincidental? Should I look anywhere else? I have a MityVac and will be troubleshooting for vacuum leak.
