Hello all..I have a 1978 with a crate motor. Recently the car has been sluggish off and on and I have not noticed anything wrong until today. When the headlights come up I noticed the idle goes down to 400 and jumps around instead of the usual steady 800. Is this a vacuum leak and would it make the car sluggish upon accelaration ? Any thoughts or info is appreciated greatly. Thx
