Engine idles nice on startup then steps down

Hi,

Ive read through the posts and found similar problems but not exactly so I have a question. When I start the car it idles up then smooths out for a bit but then it stutters a bit and seems to step down before idling up and smoothing out again. It also will drop down in idle when I pull up to a light and sit. I have changed the fuel filter,fuel pump and just changed my oil. It sounds crazy but it seems to do this more when the weather is hot. Any ideas on things to check would be appreciated.

What RPMs are you talking about? When it drops while standing sill, what is the RPM?

A lower target idle is normal as the coolant temperature increases.
