That sounds like you have a prob with the cold start system.

My guess would be the coolant temp sensor. AFAIAA there's no specific cold start system eg an extra injector etc

CTS was changed a while back, is that the only thing it could be? Suppose its not the dearest of parts to just change!

Did a little reading, the CTS adjusts the ammount of fuel, and timing to suit when the engine is cold, doesnt mention anything about idle speed when cold. Would the TPS be at fualt without there even being a code flashing up?
