[05 wagon guy]

I've got an 05 wagon throwing p0301 codes & smells of unbrunt gas everytime I drive it. Any suggestions of where to start?

new air filter would be first step
could be choked out

Some of the older vehicles had a fuel rail issue. I'm not sure if it was resolved in the later cars. Was most prominent when cold.
