Got a tip from a independent tech today to check out the OSV for a faulty diaphragm. Tested the suction on the dipstick. Started the car with the dipstick in and then removed. I heard a high pitch whine in the front part of the engine. The idle changed. I placed my thumb over the dipstick hole and the car stalled after a few seconds. I repalced the dipstick. then restarted the car. Performed the same procedure. This time the car idle slowed when I removed the dipstick and it stalled again after a few seconds.

Finally, I replaced the dipstick. and only took it out an inch. The idle dropped and the whine increased. I replaced the dipstick all the way in and the car idled up to normal.

What is the problem? Is this consistent with the OSV problem.
