If you smell gas, it could be possible that you have an injector problem. It could be as simple as a bad seal.

When the engine is cold, turn the key to the II position, but do not try to start the car. After all the clicks from under the dash stop, turn the key off, and repeat a few more times. Run a paper towel around the two parts of the injector where it seats in the cylinder head and the fuel rail to see if there is any gas leaking out.

Try swapping the injector on cylinder 5 with another cylinder and see if you get a different misfire code on the new cylinder.
