When the car reaches normal operating temperature it isles and runs rough. It does not do this until the normal operating temperature is reached. What would cause this?

Has the check engine light come on? Also, have you checked for vacuum leaks?

The check engine light is on but I cannot detect any vacuum leaks. I did recently change the oil fill cap.

Have the computer scanned to determine trouble codes. Since the check engine light is on, there will be codes present.
