smoke screen ,you are too much ,but it is worth an idea i would like.
P.S. i am planngin on mounting a pinhole camera with mirror motors and a washer nozzel connected to a certain fluid for precision sniper shooting, but enough of my madness.
My car ran perfectly immediatly after i cleaned the MAF , it was 2 weeks i took to figure it out after changing plugs and fuel filters for no reason.
Put it this way if the problem is with the IACV all you have to do to keep it from shutting down is press the gas and it will rev until it warms and no longer needs the extra air for cold/hot starts.So if pressing the gas pedal makes no difference i wouldn;t bother with it although it is always agood part of maintance.
