Wired sound

Ok this sound is kind of a ticking sound.. Stays the same and i only hear it at idle.. And I read alot about spark plugs blowing out and all.. I am kind of scared and hope thats not it.. I am about to do a tune up but now thinking about having my work do it since i work at a ford dealership.. I just deatil cars tho.. It really makes me scared I hope its not a blown plug.. My car dose have a worranty cuz my mom got it used still has a year and half left.. So should i change them my self or pay them to for 60 bucks to do my tune up.. I am going to start my car up here in a bit and see where its coming form... It reminds me of a loud injecter...B/W the car runs good dont miss are anything..

I have some but it seems to have been like this for awhile.. Cuz when my mom had it i drove it and I would check the fuilds and let it run and all..

Ok welp i let it worm up and i go all the way around the motor lissing and it just tic tic tic sound everywhere.. I give it a few revs it dose get louder it sounds like someting going up and down tick sound..

I just hope everything is ok.. But i guess i'll have a tec look at it tmw..
