why is your idle 900-1000...have a/c on or something...idle should be like 750ish...then you could bet for sure your vac number will do down

Tap on your gauge and see if it drops 1 or 2

Thats normal, I see the same thing. Sometimes my idle holds up there for awhile before going back down to 750, I already had it adjusted and I asked Mazdatrix why and John said the computer holds it up there for a little while when coming to a stop to keep the water pump moving. At 750 I see more like 16-17.
