2.5i engine

2010 Subaru 2.5i legacy. p0340,with misfire codes. 115,000 miles on car. Changed the cam sensor, plugs, and bat. Checked the wires from cam sensor to pcm. Engine idles with random misfires. Try to give it throttle and it takes in a lot of fuel, and has massif misfire in all cylinders. fuel presser is running 55 psi. Compression test 180 + - 5 psi. Timing marks all line up. What am I missing? Thank you for any help I can get.
