Question about Chevrolet Corvette
Ignition timing, cam grind of a performance cam shaft, can lower engine vacuum at idle, also check for a bad diaphragm or vacuum storage container in the system, some of the old vettes had a vacuum storage container to store vacuum because of the solid lifter motors and the cam grind they were noted for having low vacuum , so GM would use often a container that almost looked just like a 1 lb. coffee can painted black and put in in-line in the vacuum system to store vacuum so when you suddenly accelerated the headlight doors would not slam shut, it would provide enough lag time in the vacuum loss, that the storage would recover.... hope this helps...
