probably vacuum leak.

Love the pic, I had a 1970 Olds Delta 88, Rocket 350 motor...wish I still had it!!

vacuum leak is a likley possibility and simple to search for just get a can of starter fluid and spray the vacuum hoses but dont just go hog wild slow and steady and when the starter fluid finds the leak it will make the engine rev up good luck

vac leak
 

thanks for your responses i will give the carb spray a shot and see what happens

coolant temp sensor?

how is the fuel spray?
