yeah i would check scv valves next, if they are required pm parts king(lindop toyota) on here, should be able to sort you out on a price.
I suggest you buy them from genuine toyota dealership for piece of mind. I think there are around £200

Hi,
have you got access to an OBD code reader? It might give a bit more information and maybe reduce the risk in buying the SCVs.
