Quick question on Idle Hopping. I have a 99 integra 4 door and switched from a B18 to a B20 bone stock. Now I have been having this weird "Idle Hop" when I start to slow down, it will hope twice then goes to normal. Happens ever so often and sometimes it happens alot, (it kinda happens when it wants to). Car runs perfect but it just this "Idle Hop".

Specs are a Automatic Bone Stock B20 with a Idle Hop at slow.. help me out here. Oh one more thing. I still have to change my "Crank Angle" Sensor would that make a big difference?

 

could be ur pcv valve
