Hi all. My car is a 2001 honda accord v6. It sat for 3 winter months. When I go to turn it on in the morning, the car will rev while idling. Jumping between 1000 and 3000 rpms. Anybody have an idea why this might be happening? Thanks for any advice! -grisha ---

Probably the Idle Air Control (IAC) Valve needs cleaning or is faulty. You can try cleaning it yourself if you’re handy: ---

+1 to jesmed’s suggestion. If cleaning the IAC doesn’t help, then I would suggest checking all vacuum lines for cracks or disconnections. ---
