My V8 limited seems a little slow to come back to around 600rpm idle. Sometimes it wants to hover around 800-1000rpm for maybe 10-12 seconds which is more annoying than anything. Is this pretty normal?
My guess is that it's temperature related. You drive in winter, it cools a tad, so when you pull up at the lights, is keeps the revs up a little before settling down again.

Our GT4.0, when cold runs at about 1100rpm, with NO A/C on.
Once at normal operating temperature it idles at 700rpm in Drive, which according to the original spec sticker on the underside of the bonnet is correct.
When driving at normal temp with A/C ON, and stopping, say, at a red light, it initially drops to a high idle of 1000rpm, them approximately 5 seconds later it will be idling at 800rpm. But as soon as the A/C is turned off the idle drops to a steady 700rpm in drive.
I STRONGLY suspect THIS to be NORMAL.......unlike the owner!
