i am stil waiting on my honda data.. ok when i start my car is at 1500 rpms then when its at operating temp it idles normaly. then when iam driving around and i put the clutch the rpms stay at 1500 till i come to a complete stop... as i said in my other post it ran fine before the head gasket was replaced, iam thinking it could be air in coolant or vacuum leak or just a simple iacv or the the thermal valve i forget wat its called
