2005 Tribute giving me several codes and running very rough.

P0315 - Misfire detected
P0302 - Cylinder 2 misfire detected
P1450 - Unable to Bleed Up Fuel Tank Vacuum
P0452 - Evap emission system pressure sensor/switch low input

I had it in to the mechanic prior to these misfire codes and they said to replace the mass airflow sensor and the EVAP purge valve. Figured I could do this myself so I started with the mass airflow today and it's not any better. Before moving on to replacing the EVAP purge valve, I ran codes again and now am finding the misfires.

What should I do? Parts store is saying to check/replace the plugs and wires. Should I start with the purge valve?

 

I would suspect a bad ignition coil. Sucks cause cyl 2 is under the upper intake so it's more than a simple swap. I had a bad coil on cyl 3 a few years ago and decided to replace all the plugs at the same time. I would've put in all 3 new coils for bank 1 at the time if they didn't cost so much lol
