Code:
obj
    test
        icon = 'test.dmi'
        icon_state = ""
        density = 1
        Move()
            var/obj/a=new/obj/test1(src.loc)
            a.dir=src.dir
            a.Owner=src
            spawn(30)
                del(a)
            ..()


obj
    test1
        icon = 'test.dmi'
        icon_state = "trail"
        density = 1


Problem description:well when i move the icon it always pops up on the head of the trail. How would i prevent this.

well first

obj
    test1
        icon = test.dmi'// change this to icon = 'test.dmi'
        icon_state = "trail"
        density = 1

ok.... Now what...

If I understand you, you want the trail to spawn behind the head, and not on top of it.

Your problem lies in the Move() proc of /obj/test. In the new() proc, you're explicitly telling the tail object to spawn at src.loc, which is on top of the head object. Use locate() instead of src.loc to add or subtract one from src.x or src.y.

Yea, thats excalty what I was tring to do. Thanks for tip but wouldn't i have to do it fore every dir?

Indeed, you would. To make the tail follow the head as you're looking for, you'd have to make an if statement for all eight dirs:

var ecks,why = 0
switch(src.dir)
  if(1) why = -1
  if(2) why = 1
  if(4) ecks = -1
  if(5)
    ecks = -1
    why = -1
  if(6)
    ecks = -1
    why = 1
  if(8) ecks = 1
  if(9)
    ecks = 1
    why = -1
  if(10)
    ecks = 1
    why = 1


And using that little snippet, you can add ecks and why to src.x and src.y to determine where the tail must go.

Don't i have to put this in the obj? Also is there a simpler way to to the code you provided? I have no idea what you mean can you explain?

What? No! That's not even CLOSE to right! In fact, what was in the original post should be completely correct and the problem description makes no sense.

[edit] Oh, right: ..() should be changed to .=..() Otherwise it's good.

Yes, you would put this code in the head object Move() proc, before the creation of the tail object. And I believe the code snippet I provided is about as simple as it gets.

ok i narrowed it down and it worked thanks a lot. But it has these warnings
Also is this the only thing im suppuse to addd the code snippet?Cause every time i move it goes on the head then back behind.

Well, you don't have to.

mob
    var/mob
        follower
        
    verb/summon_follower()
        if(!follower) follower = new/mob(loc)
        else follower.summon_follower()
    
    Move(newLoc,newDir)
        var/oldLoc = loc
        . = ..()
        if(follower && oldLoc != newLoc)
            follower.Move(oldLoc)


The follower always stays behind his leader. It works for multiple followers, too.
