check engine light

What is your question?

My check engine light is on. I had it checked and was told the code came up as "misfire". The light came back on the next day. When the engine is cold and I first start the truck, it acts like it wants to cut off, but doesn't, like it's bogging out, and then its like it sucks up a bunch of gas and runs okay, and I can smell the gas. Could it be a clogged fuel filter? Where is the fuel filter on this vehicle?
