idle air control or possibly the fast idle tandem valve. maybe even low coolant level or air in the cooling system. personally id check the first 2 sensors i mentioned.

My Ex boyfriend just did a B18A1 Dual over head Vtec swap to his 88' CRX him and his dad did it and they had a problems. They hooked up the vacum lines wrong... and it was idoling like that... So check and reconnect your vacum lines... Now it runs fine
