It should be under the dash and is in a difficult place to access next to the glove box.

Usually from underneath the car - depends on the year.

Follow the positive battery cable to the starter. It will be at the rear of the engine, down low, next to the junction of the engine and transmission. That is where the starter turns the engine over, by engaging the engine's flywheel-which is at the rear of the engine.

Had the same problem. Is the unit hot to the touch? Mine was and that told me the motor was bad, replaced it and works fine

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 properly
