    Car Stuttering on Cold Start

    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!
