Warming up my car now. Pretty cold in ny. My rpm is jumping from like ~650 to 750. Every time the needle moves the car vibrates a little. Scary. What the heck can it be?

CCV, vacuum leak, and ICV immediately come to mind.

If this is a recent development, try not to sit in the car. Immediately drive the car after starting.

lol.

OP: my car does the same thing, and its a vacuum leak caused by a torn intake boot on my car. Not sure if yours is the same...but inspect that boot!

I just replaced the Intake boot 2 weeks ago.

I was thinking vaccum leak or dirty ICV.

While the intake boot is usually the suspect in vacuum leaks, it certainly isn't the only place. I'd thoroughly check the intake plumbing, as thats a quick and free inspection. Then move on to other possibilities like the ICV or CCV.

Yea I agree with the above. Check all the associated hoses with the CCV. Make sure the DISA valve is functioning and is not leaking where it attaches to the manifold.
