I Have a 2003 F250 SuperDuty 6.0 and i was driving to work and i noticed an orange light on the top right corner in my dash some kind of service not check engine light though, =ll=> it looks like that two lines with an arrow. i have no clue what it means

 

Engine air filter restriction. Check the filter minder under the hood (back cover of the air filter, find the coolant degas bottle cap and look almost directly down)reset it, and if it comes back or if it's been awhile, probably install a new one of these:
