ok. im in the same mess. since we have gs 400,s it a whole different story than the 300. well don't get shocked but this is a tuff fix, dealer charges somewhere around 800 dollars. i know that the manifold has to come off its in the back bottom part by the transmission, oh and you will need to replace two manifold gaskets and one plenum gasket. advice, don't let just anyone do it.
