Srange unremovable darkish faces

Hello there, i got a little problem that ive never encountered before on modelling.
There are these strangely drak faces on my mesh, its not normal, nor doubled verts, so if anyone could have a look at it for me, im posting some images, it only occurs on Textured mode.

it is not the textures, ive tried changin it as well.

Select all and try Ctrl-N to recalculate normals. If it wouldn’t help, look for overlapping or internal faces.
Also try ‘Set Smooth’ to all faces.

Check to make sure you don’t have any interior edges or faces.
this is odd though, that it would only be in textured mode. :confused:
