The cap that was on my throttle body shot off as i was cleaning it today does anyone know where i can get a replacement or what i can do to fix this?

 

junkyard.. you dont really need it though.

 

What is its purpose?

 

my bad.. thought you were talking about a plastic protective cover.. looked like a bolt sticking up at first.

 

If I could find my old one you could have the whole assembly . Mine was changed out years ago as I had the defective series starting with 3L instead of 8L, problems with circuit board . Got a new one off ebay . I would suspect lots of guys on here have old ones . I'm in fl.

 

What motor is that on ?
