Good Job Mike!! Thanks to all of you as well! This is what I was looking for!
Mike, you asked why I was removing it. I am removing it because it is shot. The spring inside is either broke or out of place somehow, because the idler pulley sporadically jumps up and down. Doesn't do this all the time but when it does, it actually causes a voltage drop and sometimes even stalls the engine at idle(when in gear). I am only assuming that this voltage drop is what'* causing this occasional stalling problem but, I have practically exhausted any and all other possibilities.
The tensioner is definitely bad though, either way. After spinning the idler pulley by hand to test it(3 differant times), and it always ran smooth as silk, I finally replaced it anyhow and the damn tensioner is still jumping.
Thanks again to all of you and I'll keep you posted, when I get this thing changed!
