Today I lifted the rear end of my 2004 Subaru Impreza Outback Sport on jack stands and removed the wheels to replace the brake pads. I removed a little brake fluid, but then realized that the pads were just fine, so I replaced the fluid, and lowered the car. Then I tightened up the parking brake cable a little -- it's now solid at 8 or 9 clicks.
When I started the car, I noticed it sounded different -- a bit cleaner actually. It was driving well, but noticed the idle was low. Then I stalled when coming to a stop. This never happens, so I'm wondering if maybe lifting the rear end could introduce air into the fuel line or something like that? I don't think the parking brake is affecting anything -- the drop in RMPs at idle was sudden and not related to attempts at driving.
