2001 Supercrew 5.4L

Between 2nd and 3rd spark plugs on driver's side, there is a tube/hose that goes into the engine block. Inside the tube is a coil/spring-like device, and the tube is connected to an electronic device outside the motor. What is this part? Thanks!!!

 

IAC motor?

 

pcv valve? does it plug into the valve cover?

 

Thanks for the help, guys! Maybe IAC, but after looking at a picture of a replacement one, I'm thinking not. Here are a couple of pix. The spring actually extends down into the engine block, encased in the tube from the other picture. Sorry, but I know very little about vehicles and identifying parts, however I am good at replacing parts. Appreciate your help!

i dont see any pictures.....

 

Oh, thats a simple plug boot replacement. You;ll be fine!

 

I appreciate the help, and the good news! The truck got pretty loud when it spit out.

 

wait the truck was loud like a spark plug blew out.... u got more than a simple coil pack problem if thats the case

 

The coil pack is usually held in place but a screw, however the metal bracket had rusted/broken. The tube has a split in it, which makes me suspect the engine compression simply blew it out of the hole. Is there something more I should be looking for? Thanks!

yea that slips over ur spark plug... only way that would really pop off is ur spark plug blew out or is blowing out... is there like a loud poping noise under the hoood? also which ever cylinder it came outof look down in the hole if possible to see whats going on... start it see if theres air coming out of that hole also
