What psi ? tire , fuel system

you have to run the car then tow it or else you will fry the transmissions planetary.

yes, normally it does - sometimes (if you are lucky) it is only a loose belt which can be replaced and adjusted:

Not much fun... so many beauty covers and such to take off first.

timing is not adjustable on cadillacs,you need to hook up a scanner and check for codes or use the control panel on your dash to pull codes,good luck.

have u replaced the bulb? i believe some tail lights (all?) have 2 fillaments in bulb for tail light (running light) and using both for brake... blinker/ signal is a different bulb usually- that way u have running lights/ break lights at same time ur blinking.

Many Caddys have/had small "radiators" for heat to the rear passengers located under the front seats. Most shops (or owners) never check them or know they exist.

The only way to be sure if a fuse is blown is to remove it and check it with a multimeter - looks can be deceiving! There are several radio options for your car, some which also involve an amplifier with a fuse separate from the radio. Since you did not indicate which option you have, the place to start would be fuse 21 in rear fuse block (under rear seat). The amp fuse would be 63. See the diagram in the fuse box for locations. If a fuse is not the problem, your radio is probably toast.

Try filling it with a top grade premium gas.

What sensor are you speaking of, there are about 100's of sensors in your car and at least 10 that deal with some type of pressure. I am sure someone can help with a little more information provided.

could be your oxygen sensor or catalytic converter.. You may check for leaks in manifold as well.Mass air sensor could also be at fault.

Plug a diagnostic computer in to the EODB port and the device will display error codes on screen, you can then cross reference them to find out the areas to check.

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.

Buy a EODB computer and plug it in to read the codes.

If your card has a EOBD plug you could buy a cheap device to read the error codes.

Only the Stations saved can be reprogrammed. Check or replace the fuse .

Open the gas line before the fuel filter (or right after). Then, find the fuel pump relay under the hood, pull it out, and bridge terminals 87 & 30 of that relay. At least, this is the case with earlier GM models. A small jumper wire bridging the terminals will cause the fuel pump to run with the key on.
