Can a intake manifold leak cause a misfire?

Please note that RTV is not to be used on the entire gasket; the gasket should be installed clean and dry. RTV should only be used on the corners of the gasket and/or stepped casting areas that have a gap. Using a small amount of RTV will fill in those areas to assure a leak-free assembly.
