    Did you get any codes at all? If Check Engine light goes on, then there must be error code!
    If you post codes here, we can say, what they mean - also they are in factory repair manual...

    Then it must be broken computer/MEM-CAL card in computer(ECM=Electronic Control Module)...or just corroded contacts/connectors.
    Try clean them and check again. If nothing happens, then its broken memory card...and this messing some sensors - and idle isnt right...
    But about this noise in front drivers side of the engine - check first engine belt...maybe this noise coming from alternator/or other bearings?

    This is bigger job...
    ECM(little metal box) is located in the right front corner of the passenger compartment under the instrument panel. there are colour coded connectors attached to the ECM - try clean those and check then again....
    A good factory repair manual will help you much. I recomend to buy one...

    Well, i have Haynes repair manual (#38031), but it is not explaining all areas (like transmission - "it must be repaired in special shops blah, blah"), but in most of cases its useful.
    Electrical and sensors chapters are almost perfect, others are good...
    For usual and daily use its OK, but i´m sure, someone here can recommend better and sophisticated manuals....
    For my ´67 Eldo i bought CD from Gearhead Cafe it is IMO way better choice (it contains more books too) - you need only good printer.

    Where did you learn sooo much about Eldordos. Like you probably know i have a 92 w/ 4.9 and i want to know everything about it b/c i love working on cars. I don't have much money so i like FREE information. If you have any websites that you recommend besides this one that would be much appricated

    I learned with working/repairing my car - and it is´nt so much, as you think I had to learn many things, cause we dont have here good Cadillac services. One and only is too high priced and they repair better Saab and Opels, than Cadillacs (they know only, where put oil and gas, i think ).
    But in internet you must find lots of good sites (this site of course too ) - you just find a bit here and a bit there.
    This is one Very good site
    Here is good site about sensors and what they do

    I have a 92 Eldorado myself, it's a quantum leap forward from the 87 I had a few years ago. As far as a manual goes the only one I could find for a 92 is a Chilton's. It's not great but it knows more than I do. They're constantly on Ebay, and try Half.com for a used one. The car's also old enough that they should be showing up in used book stores by now.
    Fortunatley, I haven't had the problems you have so I can't really help. But in the past I've been able to call a parts store and ask what individual codes mean.
    Good luck.
