Deville :: 97 Cadillac Idling Rough - Service Engine Light Blinks On / Off Continuously
My car is idling rough and the Service Engine light blinks on/off continuously. I ran the codes and they are P0301, P0401 and P1258. What this could be? I changed the plugs, wires and ignition coils about a year ago. Catalytic converter was replaced around the same time but the O2 sensors hasn't been changed. Could that be the cause?
View 1 RepliesDeville :: 98 Cadillac Won't Start - Check Engine Light Came On
Recently my check engine light came on on my 98 Cadillac Deville. I went to Autozone and got a free engine diagnostic and was given a printout of a bunch of stuff I did not understand, the technician told me it was just an issue with the light, and it could be fixed with unhooking the black end of my battery for 10m. Just a little bit ago, i popped the hood, and touched the black end of the battery to see how i could unplug it. When i touched it I heard a click and now there is no power to my car. Every time i jiggle the negative end I hear a click from the right side of the engine and nothing happens. I did not even unhook the battery.

1995 Cadillac DeVille 4.9 L Check engine soon light comes on, battery voltage high. When I increase speed the head lamps get brighter when I decrease speed the head lamps get dimmer. I changed the alternator because that's what a mechanic said I needed but I still have the problen battery voltage high. Will this damage the battery or other components? Should I stop driving the car.

I recently had a lot of repair done to my 2003 cadillac: new bearings in both front wheels, new power steering line, rotors turned, cv axel replaced.I also bought new Michelin "Symmetry" tires as I am taking a long trip.
I had Toyo tires with some wear and had them rotated at another place other than my mechanic's. After that I noticed the humming noise in the front; it sounds like it is coming fron the driver's side and is most noticeable when I drive 35 or 40 mph. My mechanic said he checked everything carefully and couldn't figure out the problem.
Ford 7.3L Power Stroke (1999-2003) :: Service Engine Light At Acceleration Only
So i replaced the faulty injector and the truck starts up great and runs great. The only issue is that now when i accelerate, the SES light comes on until i let it up a little. If i am at cruising speed or just a steady speed the light goes off. I havent checked for codes yet because the light didnt stay on. I have AE and know how to use most of it. Is there something i should be looking at? Could it have something to do with the Blue/Gray CPS i installed or maybe there could still be an air bubble in the oil rail from when i drained the rail ? I have a DP tuner and stage-1 injectors. Regardless it sure is nice to have my truck back out on the road. It was a horrible 3 weeks without it.

I have a 92 Deville. I drove a pretty good distance today and on the way home stopped at the store and left the car on in the parking lot. I got in and the engine died as I tried to pull out of the lot. When I try to start the car all the lights come on but nothing happens, no clicks or anything. Lights don't even go dim. Could this be the alternator? I know that the starter suddenly dying won't cut off the engine like that. Everything seemed fine before idk what gave out?

My car started overheating and when I got under the hood I noticed that one of the belts was torn up pretty good. I'm guessing that this belt runs the fans or something. I am wondering what the name of this belt is and how hard it would be to replace?
The picture looks too small to be able to see it, but it's the belt on the right side of the engine block, next to the oil dipstick. The second picture loaded upside down.
Cadillac - Seville :: Service Engine Soon Sign Came On
The service engine soon sign came on awhile ago. I immediately took it to a garage and they said they can't find a code. My mechanic friend checked it and found a lean combustion condition. What could be causing this issue and what can I do about it. This yellow service engine soon light is driving my nuts!!!

My wife called to tell me that her Camry would barely pull away from a standstill this morning. Very sluggish until about 2500 rpm, at which point she said it took off normally. This accompanied by the Check Engine light, which just appeared this morning. I haven't been home yet to check fluid levels or take a test drive. Anything in particular I should be looking for?

At times when going to start our 1998 Caddy you can turn the key and ..... nothing happens, no clicking ... nothing. Everything else works but it is like you are not even turning the key. Is there a weak spot on these cars?
I am familiar with solenoid/starter issues but this seems a bit different for some reason.
Cadillac - Deville :: 1992 - Running Rough Again?
I have a 1992 Cadillac DeVille with 25,000 miles on it. It’s never been driven in the winter and garaged when not being driven.Last year, it was running rough, so I took it to the dealer. They changed the spark plugs and wires. There seemed to be some improvement after that. After about 500 miles, it started to rn rough again. I returned to the dealer who changed the spark plugs again and replaced two of the fuel injectors. Still no improvement. A few hundred miles later, I took it to a local mechanic. He replaced four more fuel injectors and there seemed to be some improvement.After another few hundred miles, the engine started to run rough again, the fuel dropped down from about 20 mpg to 10 mpg, and it stalls at traffic stops or if the brake is applied. After 30 minutes of idling it will use 5 gallons of gas. There are no strange odors or visible leakage.

04 deville. Trans is stuck in gear. Or seems to be. Car is off. Crank car, starts fine so gear selector/neutral safety switch is ok? Car is running, shifter is in park, take foot off brake amd car moves forward. Since its in gear. Apply brake, shift to neu or rev and car will still move forward. The 2000 caddys had an external neutral safety switch. The 04 cars have an internal switch. If that has an bearing on discussion. Could trans shifter linkage inside trans be messed up? So spool valve in trams is always in gear but shift selector works properly so car can be started?

1995 Cadillac DeVille Base 8Cyl 4.9L - Transmissions & Drivetrains check vehicle soon, error code p039 TCC engagement Torque Converter Clutch. I looked up what error code p039. How to correct the problem.
The problem I think is the torqure converter sensor or pcm = Powertrain Control Module / prom = Programable Read Only Memory is not working or sending the single to the computer.
The trans does not slip and drives great. Is there a chip or module I can purchase if so where. How can I find out how to repair myself if possible.
Cadillac - Deville :: 1991 - Chugging Persists After Heating Up?
I have a 1991 Cadillac DeVille sedan with about 150,000 miles, I purchased this at an estate sale. As soon as I bought it, I replaced the spark plugs, wires, distributor cap, rotor, serpentine belt, power steering pulley, and of course changed the oil and oil filter. I was getting about 14-15 mpg (compared to 12 when I picked the car up). And the car ran good, not like brand new, but good. About a couple of weeks ago (as it started getting hot) the car would start chugging, backfiring and stalling, only after about 20 miles of driving (my commute to work is 35 mi), so I would spend the other 15 miles driving with four-ways on going at most 30 mph. But, on the drive home (at 2 am) I would have no issues. So, I got sick of that fun and changed the PVC valve and fuel filter (which looked like the original) and with every fill-up in addition to using 93 octane gas (as directed) and fuel injector cleaner, the gas mileage is around 10 mpg and the chugging persists after heating up. Two things to note,
1) the fans for the radiator do not turn on at all, and
2) the catalytic converter doesn't smell like rotten eggs.
