Since I've changed the TB/WP/ etc. and still have the screeching on start up is it the TB tensioner that I need to replace? Plus what else would I need?
And on top of this, after driving it around for over a week, last night it just up and would crank and not start until the 4th try. I think it may be crappy fuel as I let the kid take and put gas in it. will add some additive and see if that clears it up.
