For the last few days, when I start my Q it will idle at 1500 rpms, whereas before it would start at 1000 and quickly settle down to 700.If I shift into reverse/neutral/drive then shift back into park, it will idle at the normal 700 rpms.Other than, it's running great.

Anyone know what's up?

Let it warm up. For the last 2 years mine starts at 1500 and settles down to 800 after about 60sec.

So it's somewhat normal? But why the change?

Just moved and now it's back to starting at 1k and settling to 7/800.
