I installed the v2 yesterday. This morning woke up to come to work and got down the road and it was idleing funny. When I came to a stop it turns off. Anyone have any ideas?

 

you may want to try an idle relearn. I am pretty sure on the civics you have to start the car with all the loads off and let it run so the cooling fans cycle on and off 3 times. And the car may not like that much air coming into the engine.
