The throttle cable wouldn't have anything to do with whether or not the engine will idle.
If you actually ever look at the throat of the TB, you'll see a hole about the size of your pinky. That's the idle bypass hole. When the engine is idling, the throttle plate is fully closed. No air flow.
The IACV has a poppet valve in it that meters and measures the air flow at idle.
On the aft side of the TB, there is a brass screw. If you're looking at it as if to look down the throat, it will be at the top left corner. It might be covered by grey paint. Scrape it off to reveal the brass screw.
With the engine off, screw it down all the way until it stops, but don't let it get tight. It's a bitch to break it back loose. Back it off two full turns. That's where it should be as set from the factory.
If it still won't idle, and simply cuts off, check the throttle position sensor with a voltmeter a paper clip. Connect the common ground lead (black) of the VM to a bare metal bolt, or to the VC ground. Insert the paper clip into the back side of the middle wire on the connector for the TPS. Attach the hot (red) lead to the paper clip. Put the key in the ignition in the ON position. Read the voltage in the closed position. It should be 0.45v +/-.02v at 0% throttle. At WOT, the voltage should be 4.5v +/-0.1v.
If the voltages are good, go ahead and replace the IACV.
Forgot to ask, do you have any CELs?
BTW, I got that from the factory maintenace manual for the 1994-1995 Acura Integra (OBD-I). Since you have a B, all of the TPS voltage values are the same across the B spectrum.
