Ok, so I was reading in Haynes how to change the timing belt, it mentioned something about installing a tension spring to the tensioner, I never did this, could not installing this spring [censored] with my timing? when i did my timing i used Mitchell, not haynes, where do i get this from? autozone said they didnt have it... perhaps that could be why my valve timing MIGHT be off a bit...
