serious Idle issue.

When I first start the car its starts revving up and down untill it warms up. I have no clue what it may be. Has anyone else had the same problem? What should I check for. Any help will be appreciated.

how badly does it go up an down. alot or just a little. mine does it just a little about 50+/-. rpm. If it is alot you may have a vacuum leak.

Check your coolant, might have air bubbles in there. Could also be the iac valve or a leak in the intake manifold.

I put some transmission fluid a few weeks ago when this first happened and it went away. Yesterday it came back. How do I check if its a leak in the intake manifold?
