If the cold start rpm is low it could be due to various reasons.
Do you have coolant losses or overheating issues?
Are there any trouble codes?
After warming up, what is the idling speed and does it change when A/C is turned on?
Are there any performance and driveability issues?
Try cleaning the IAC and throttle body for a start.
