  1. Hello! I have a 1990 Cadillac Deville, 4.5L V8 PFI, 75,068 Miles. Today I was driving and all of a sudden the SERVICE ENGINE SOON light came on and both the Fuel In Tank and Electronic Climate Control read outs started showing a “d”. (See pictures in links below). https://i.imgur.com/urkMrQF.jpg https://i.imgur.com/jnIw9xU.jpg https://i.imgur.com/VXwOqxk.jpg Gallery On top of this the Air conditioning fan started blowing air from the dash, not hot or cold, just ambient temperature air and I can’t change the Climate Control or see the fuel level anymore. When I got home I unhooked the battery to reset it then turned the ignition on without starting the car and pressed “Off” and “Warm” on the climate control so see if I could get a code it looked like a code flashed (to fast for me to read), then it read 000 and would blink over to .7.0 occasionally. I replaced some vacuum hoses that were kind of bridle as well as replaced the o-ring that goes between the air filter housing and the carburetor since it was cracked. I hooked the battery back up and the dash read-outs still showed “d”, SERVICE ENGINE SOON light, and the air was still blowing from the dash. I called around and neither Auto Zone or O’rilleys has the OBD 1 connector to scan the older (pre 1996) cars. The car runs great so it’s hard to trouble shoot whats going on, and I cant find anything at all online about this specific problem. Any ideas or suggestions?
  2. Ten degrees F this AM in New York. Car is parked outdoors. 1997 Eldorado T purchased new, properly serviced in good condition, 133,000 miles. Got in this AM and had a hard start. Maybe not hard, just an unusually long crank before firing. Battery is three years old, alternator charging at around 14.4 while running. Once it kicked over, ran fine and smooth but the "Service Engine Soon" light came on and stayed on (amber light). After driving for a bit I ran for codes and got the following: PCM P0325H PCM B0533H PCM B1971H PCM B1983H MMM B2144H I looked them up and the first one has something to do with the knock sensor, the second with the fuel sensor. I don't understand the third and fourth, and the fifth one has something to do with the left side mirror position. The car seems to be running fine, nothing I can feel from thr driver seat. But the "Service Engine Soon" light won't go off, even after three driving cycles now. All codes are History codes, not Current, so I wouldn't even be especially concerned were it not for the "Service Engine Soon" light. Before I bring this in to a mechanic, does this look like a costly problem to repair? I wish I could provide more information. Any opinions would be appreciated. Thanks much.
