Question about Cadillac Eldorado
What do I adjust to lean it out?
Can't adjust anything-- it is fuel injected
May be able to adjust the TPS Sensor, but
I doubt that will be part of the lean codes
or whatever you have
May have to mail the injectors away to be cleaned
& flow tested
Have to check for OBD1 Codes,first
Have to check,test & possibly replace the oxygen sensor
Have to test the CTS -coolant temp sensor, to make sure it goes
into closed loop & you have control over the fuel delivery
Too lean-- is either a RICH condition being corrected by ecm
or a vacuum leak & thus lean condition
Many other items & reasons as well
You will need vehicle experience with OBD1 Systems
& an understanding of the DFI Fuel System on the caddy
to work on it.
You say running too rich,what testing told you that?
Too lean & being driven rich, so that are the codes you see !
Dirty worn out injectors-too rich
Fuel Pressure regulator failed-too rich
There is good video on rebuilding a throttle body on
You Tube Video, you can watch & see about pressure
regulators & injectors on your type system
Check every vacuum hose in the engine compartment FIRST
for vacuum leaks
Do not forget about worn out & partially blocked exhaust converters
& clogged gas filters,not related maybe, but still have to be working

SOURCE: My 351 is running rich
use the air and gas flow adjustments on the side of the carburator to adjust the rich/lean flow of gas. there is a srew on each side of the carb to adjust one is for air the other for fuel. the one on the driversside is for the fuel and the one on the passenger side is for air. you have to turn them slowly til you get the desired results

Push both OFF and WARM buttons together (and hold for 5 sec.) on the A/C control panel. Read what codes appear . It can be cleared by pushing OFF and HI the same way. Hope this helps

its time for new brakes..read your owners manual...brakes will tell you they need replacing with squeeks or chirps and these go away when you press the pedal.

This should be a a HT-4100 engines. Distributor rotation is counter-clockwise. The driver bank is 1-3-5-7. The passenger bank is 2-4-6-8 from the front of the car. The firing order is 1-8-4-3-6-5-7-2. Just like a small block chevrolet
