Hey fellas, I have a manual transmission 89 Iroc.

When I start it its all good. A few minutes into the drive, it has a tendency to idle out and shut down if and when I go into neutral. When the car is fully warmed up (10min or so into the drive) it won't idle out. Its just that 4min-10min window when the car tends to idle out when in neutral.

Also, when its real hot outside (i live in southern Cali) it doesn't idle out as much. hmmmmmm.

Thanks guys for any help you might give!!!!!!!!!!!
