    1994 Cadillac Fleetwood Brougham diagnostic mode codes

    I Have a 1994 Cadillac Fleetwood Brougham 5.7 Lt1 and I have found some websites that have posted some of the codes in the diagnostic mode but not all of them because i get some codes like 00-63 witch is right oxygen sensor problem but then i get a code like 05-140 and i can't find anywhere to show the codes like 05-140 just the two digit ones like 00-63 Any help on that would be great of course my
    car didn't come with a service manual And if any one could please find me a free version of the manual i would appreciate it also.
