i have a friend with the same problem it could be a few things try checking ur cam timeing check ur fuel presure

IACV or low coolant

If it's doing it while the car is cold, it's most likely the FAST IDLE VALVE.

The Fast idle value will increase the air flow while the car is cold. Like auto choke.. It allows more air in, creating a higher rpm so car warms up faster.

happened on my integra..

Idle air control or possibly a vacuum leak.
