95 S320 Starting Issue

Just recently my 95 S320 has been acting strange when starting in the morning. It's summer time here so it's around 80 F in the morning.
When I start the car it accelerates for a moment then idles down to normal speed. Not a big deal since I use the car everyday but I hate it revving up more than necessary when there isn't much oil in the system (ie dry start). I doesn't do it during warm starts.
Any ideas? Thanks, Bob
