Hey guys,

At idle my car usually revs at 800rpm but tonight when I hit a red light it was reving at 1000rpm and would'nt go down to 800rpm. It was like this untill I shut of the car and started it back up. Know it seems to rev normal!. .

What could cause this problem...is this a sign of something about to break?..thanks in advance

That would be an idle issue, not a rev issue.

Your IAC might be sticking.

Good luck.
