Problem with rpm.

Hey, any one know why when I start the car up in the morning or when it's cold, the rpm would jump a up and down and even when I start driving and it won't go away until the car is warm up. thanks

If you had and read the Mazda manual; you would know that two systems control
cold starting and idleing: ISC and AWS.

Trying adjusting your throttle set screw and/or air bleed screw. Try both ways: more or less air.

How many rpm's does it jump? Is it rock steady when it's warmed up?

it jumps around 600- 800 when it starts up and it's steady after warm up
