possible vaccum leak or idle air control issuek

You mean you have no HAVC Blower at allin heat or a/c?Check the fuse firstThen put battery voltage directly to the blowerIF you can get to itAfter that you need to have diagrams of the systemselectrical,, as i suspect a module is involved thereIf your question should have asked about no air conditioning& your blower does work,then you need a shop with traineda/c folks

Never seen this car but all engines have the temperatrue sensor in or around the cylinder head region so look for a sensor on the head that goes into the water jacket

Remove exhaust crossover pipe and oil qty level sensor, Once you undo bolts if you find that it wont come off that means this model has bolts that cant be accessed without removing powertrain cradle.

Bank 1 Sensor 1 O2 Sensor voltage control wont allow more fuel.Check sensor for loose terminal, dirty contacts, burnt or shorting wires, vacuum or exhaust leak.If all that checks out you have a bad sensor or PCM

Code 133 is for a problem with the O2 sensor for bank one - the one in front of the catalytic converter. The signal coming into the computer is not switching back and forth between rich and lean as fast as it should. Most of the time the sensor is at fault, but it would need to be checked out before it is replaced.

Check out this thread and take your Caddy for a couple of Wide Open Throttle runs on the Interstate. Clears out the carbon buildup on the rings that is causing oil blowby.

I have torqued all Aluminum Wheels & Steel to 80 lbsfor the last 27 years with no problemsThe actual recommended torque is probablya little higher, but not needed & you chance damagingthe wheels & other brake rotor issues, if you go higher

Without testeing anything any components physically - it could be the fan motor or a fuse or relay.
