Don'tSay, the evap code is probably from the hose
that was disconnected at the spare tire location in
your other thread. It appears to be an evap cannister
purge valve, and will trip a code if it's not working
correctly. These evap valves start sticking as the miles pile up.
That's probably not causing the miss, however.
As was stated, maybe check the plug and wire on the
number 4 cylinder (driver's side front).
