Hello everyone,

 

When i start the car when cold, engine runs rough at idle...

 

When warms up runs smoothly.

 

Any ideas ?

Coolant temp sensor would be my first suspect.

Thank you for your prompt reply,

 

Do you, by any chance, know the part number to look for in order to buy a new one to test it ?

Given you have a vRS and not a 1.6 I'd suspect you should think about a SAI pumpectomy.
