No screw - fully computer controlled. Also, there is no idle control sensor - just a throttle position sensor (TPS) and an idle air control (IAC) motor. If you are replacing the IAC, clean the throttle body ports VERY carefully using a recommended solvent.

Tying to find crank sensor for 2002 Cadillac Seville std 4.6 liter

This answer covers 1999-2005 Cadillac Deville, Eldorado & Seville.
Example Engine:
2002 Cadillac Seville STS 4.6L SFI DOHC HO 8cyl.

This engine has (2) Crankshaft Position (CKP) Sensors: the Upper sensor is CKP sensor B, and the lower sensor is CKP sensor A (this is included for the OBD-II DTC codes - P0385 references Sensor B = upper CKP sensor, whereas P0335 references the lower CKP sensor (sensor A)).

Both crankshaft position sensors are located in the front of the engine just above the oil filter adapter. To access both CKP sensors, jack up vehicle on the passenger side, remove the oil filter, and the oil filter adapter, including the Engine Oil Pressure (EOP) switch. See illustration.
The ARROW points toward Front of Car.
1. Upper Crankshaft Position Sensor (B).
2. Lower Crankshaft Position Sensor (A)
3. Engine Oil Pressure (EOP) switch
4. Engine Oil Level switch
The Oil Filter is the can-type object below the oil filter adapter, which includes the EOP switch. Recommend: remove oil filter with an oil filter socket/strap wrench, since it's close to the oil pan.

Where is the idle screw located. Is it on the idle cylenoid. Probably spelled that wrong.

on the 4.9 liter v8 the idle speed control motor is is located in front of the throttle body it has two miniature pulley's on the side of it where the throttle cables are, there is a screw located on the idle speed control motor which can be adjusted but i would not sugggest it they are known to go out and they do affect the idle when they are malfunctioning its fairly simple to change and the its called the idle speed motor made by duralast they are seventy two dollars at auto zone the pic. of part i explained1_19_2012_4_12_07_pm.jpg

2001 Cadillac Deville coolant bleed screw Location??

I had the same problem with my 2001 Cadillac Deville, like you I had replaced literally everything thermostat, water pump, radiator, temperature sensor, reservoir and cap, hoses etc....I didnt have any leakage. I was told I had air in my coolant system. After a lot of research and running across the right mechanic I was able to locate the bleeder and remove the air from my lines. No problem since. The bleeder is located on yhe left side of the radiator on the crossover, mines was sideways..Hope this helps someone before they spend money for new head gasket problems..Try this it helped me....
