Poor warm restart idle

[Schaible, David]

You also can use ventil sauber from lubro moly,  however, I don't
believe the 20v i5's get intake valve buildup.  The bmw's definitely
did, so I would ask that guy to clarify where he is coming from on this.

However it is a cheap fix if it works and very easy........
