Where the water lines connect to the pipes on the side of the engine; should they be blocked off individually or joined together? or doesn't it matter?

My next assumption would be maybe a sticky throttle, i say as my sister loaned her car to someone and it came back with a high idle, it stopped the next morning after dad serviced the car. Only posible explanantion was dirty throttle plate.
Insert witty comment here....

when the car is idling try blocking the small holes inside the throttle body itself. I had this problem with mine when changing from a rwd inlet to a cut n shut....i dont know if im usuing the correct terminology but the "galleries" inside the tb itself weren't sealing against the face of the inlet (if you know what i mean)
ahhh i see....
yeh u dumped a wwhole can of carby cleaner in it's guts.. was dirty as dirty can be!! worst i had ever seen..
i have changed between 2 throttle bodies, and they both have the same thing.. getting some new injector o rings today, it really could use them anyway!
the coolant ones you can leave.. they do nothing.. the other 3 on the other side i have blocked individually.. but i will most likley use that whole plate over the base..
You've got to find where the air is coming from. put your palm over the TB and if the engine still runs youre looking at manifold gasket/injector seals (unlikely) or cracked/holed manifold.
The most common cause of a high idle is a blocked up isc body. I strongly advise against plating it off. The system works so well when in good condition/set up properly that its a waste to ditch it.
How do you unblock the isc body? can you still run it with only the water lines connected and the rest blocked off?

it seems like the ISC was stuck in one position.. i tried to free it with copious amounts of inox and screw drivers.. as i know it can be a good thing.. but with no sucsess.. i blanked it off for now, and will lookinto a spare TB that i have.. which concidently had the exact same problem (the spare one i put on the car)
You can try blowing it out with air. All the other lines can be blocked off and usually are as these are idleup circuits for AC and PS.
My car idled at 2-3000 when I first installing the engine.
Put my finger over the idle up hole on the TB and it idled correctly. Tried disconnection coolant lines but that didn't help (if lines are disconnected isn't you cold-idle up always going to be open?). Anyway blocked mine off and now I need to kick start it when cold. (gives the car character hehe)
I boiled the cold idle valve and it does indeed work like a thermostat. Later found my problem to be a blocked coolant passage feeding the TB. oh well, never looked back. one less worry and also makes your TB look much neater.
I tried using the original gasket but gasket sealer works better when I did mine. You also need shorter screws.
also note a JDM TB is not interchangable with a ADM. You need to use the correct manifolds as airports are on opposite sides - i tried.
i don't think that actually makes a difference.. yeh the plate works.. the only thing i need to to do this when it's bone cold is play with the throttle for a few secs.. then she'll idle fine..
