Hesitates on acceleration

Hows the spark plugs ( autolite iridium xp .044 gap ) start with a tune up which includes spark plugs and a air filter and see if this cures the hesitation.
I am having the same trouble i can be at idel and it wants to cut out. Also i can start it to warm it up and it will just die. I have replaced intake gaskets,o2 sensors and fuel filter
