vz sv8
Hey guys just got a vz sv8 ls1 everything stock 260000 kms , car runs good drove 5 hours home everthing ran well good power etc but has a low idling problem will stall sometimes at lights etc , when I first start it it revs quite high around 900 or so then if i give it a rev it drops right down to 200 or so ,also I'm a bit worried about a head gasket as there's milky **** on the oil cap and water in the lid also on start up there's a fair bit of water coming from exhaust (stainless)
Cheers

You could start by cleaning the MAF Sensor (Mixture Air Fuel) using dedicated MAF Cleaner available from all good Auto Parts Stores.

Possible vacuum or manifold leak? I'm having the same sort of issue, except when my shift kit got done it ran fine at 650 rpm for a month then dropped back off.
