Too late. I used my smoke machine.
It works great. Turns out there was a hose disconnected from the "octopus".
So there was a pretty big leak. I reconnected the hose and verified no leaks after that.
I went for a drive and the car seemed abnormally smooth and quiet. Idle was smooth.
Then, just about when the car reached 200 degrees or so, I got major jerkiness.
When I got home, I noticed a strong sulfur smell. I had noticed it before, but never thought about it until I saw a YouTube video that mentioned it as a symptom of a bad O2 sensor.
I have also verified that my gas mileage has gone to hell.
I usually get about 17.5 MPG. This time I got 13.3.
Now I did not disconnect the battery after fixing the vacuum leak, so maybe the car had learned to be rich all the time?
Or maybe I screwed up the O2 sensor by running with the vacuum leak?
