Message My car has a few different problems.

The first one is it takes longer than normal for the rpm to drop when I come to a stop light and throw the gear into neutral.

Secondly, the idle will be at different rpms each time I come to a stop light. One stop it'll be at 1000rpm, another stop it'll be at 700rpm.

Are these two problems linked up?

Anyone have these problems before?

Also, the car's vacuum pressure is a bit low, hovering around -470mmhg, but sometimes it'll be at -510mmhg (where it's supposed to be) I already did a vacuum leak test, but could only find one leak coming out of the driver side intake valve cover...it was an extremely small leak, which I don't think will cause vacuum lose of this degree.
