dealer replaced my manifold once and f'd all sorts of things up....they had to keep it a month and a half just to fix everything they screwed up...I thought it was funny...maybe I would get a new engine..but it didn't hapen..and I wound up walking to work everyday for that time.
I guess the only way to be truly at peace is to gut all VX's everywhere and replace them with better working, fuel efficient, and more powerful ones...
