Folks,

My '79, 450 SLC, 4.5Ltr, V-8, w/98K orig miles, engine will race when I start it when cold, but not necessarily cold outside. This process takes quite a while before it finally drops to normal idle. The idle speed will increase to 15-1600RPMS until the engine warms. THIS IS NOT NORMAL.

My old ford would do this with the automatic choke! They outlawed automatic chokes years ago!

Pls advise

Thanks
