Every time I start my v8 the first time any time really it just wants to stall and cut out. It is worse in the cold mornings, the second turn of the key it is normally fine, but sometimes cuts out when I switch between N/P To Reverse or Drive the first time.

In the morning I have to hold the throttle open a bit until it gets warm and it idles rough for a few seconds. I have changed the Rotor Arm, Dizzy cap, Leads, Plugs, fuel filter, air filter, all the vacuum lines checked/replaced and a new fuel pump. Looks as though it has had a new coil in recent times and a new dizzy too. I'm stumped as what to do next none of this made a difference, it runs perfect all other times.
