I agree with blue. The "correcting" of the vacuum deviation would suggest that the problem is not static, and lifter sticking can do this. I would sea foam the intake and crank case to see if that makes a difference. From personal experience I can tell you that this can fix sticky lifters so long as nothing mechanical is broken.
