Default Re: spark at the plugs

Update;
Finally warm enough here to get the car out and put a few miles on it. Still having the same issue as described above. I sprayed a can of carb cleaner into the carb at fast idle and that did absolutely nothing. As per Rick r's advice I examined the intake and could find no holes or cracks anywhere. Just to be sure, I changed the intake manifold and the problem is still there.
I'm pretty sure it's firing on all 8 when I'm driving because there doesn't seem to be any loss of power or sluggishness and I can drive 50 or 60 mph with no problem.
Thanks for any input, Doug.
