I assume the bottom facing ports are the water lines..
but what are the other ones?
i have played around and found if they are open they hold the idle up to about 1200-400RPM idle hot or cold.
How do i activate the abv for cold-idle setup again? (it only starts at 800RPM, and stays there hot or cold)
i know the top to the right are power steering functions (smaller size hoses) these are blocked off
but what are the lower ones facing the firewall of a fwd layout
