Well, my TSS is original. Replacing this sounds like a good idea, after searching and finding that many people have had to replace it. So is this easy to replace? and where is it located? Also how much is the part and can it be purchased at auto zone?

Thanks guys for all this great info. You guys have really helped me out.
