- go Red as a guess.
You could use 02 compliant ( i.e. not diruptive to the o2 sensor - like wurths ) throttle body cleaner.

The key is to dissolve and wash away the oil/grime build up inside the air apeture ( Sp?) part of the ICv.

3-5 mills is the gap you should see when you look up in to the part of the ICV that connects to the hose ( large one ) underneath - which is where the air goes into the intake manifold.

Check it once you have removed it first to see how much gap there is- and do not forget to replace some lube with wd40 or clean oil - so this gate can swing easily.

Hope this helps.


The only constant is change.
