So I guess during the design phase they Bosched things up?
I know, bad joke.

Now regarding seafoam, that is definitely first on the list, obviously before new plugs. Is this a two person job? I've seen videos and usually someone is revving the engine while another is pouring it in the throttle body. Is there sure way to do this without locking things up? I also read differences as far as what lines to have it delivered.
