SOURCE: Ran out of gas and now she won't run!

i would say that you have a bad fuel pump or if you have a carb on it the float inside the carb is stuck check these and i'm sure you will find it's one of these.

SOURCE: 95 cadillac eldorado engine stalls rough idle check engine light is on

My son has this same car with the same problem. So far after tune up and other process of illimination, the problem points to the catalytic converter. If it is clogged you will get this problem with the rough idle and stalling. Look under the car at night after running it and see if the catalytic glows red. If so you need a new one. Hope this helps.

SOURCE: RX300 Engine Stalls when I take foot off the gas pedal.

The Idle Air Control (IAC) valve is clogged. This part feeds air to the engine at start-up and idle when the throttle bodies are closed. I removed the throttle body assembly from my 2001 RX300 and separated it from the IAC. After a good cleaning with throttle body cleaner the IAC was good as new. I later decided to replace it during routine maintenance. You can pick up a brand new IAC on eBay (genuine Lexus/Toyota part). The dealer will want upwards of $400.00 for a 45 minute job (all you need are basis hand tools).

96 cadillac eldorado etc battery not staying charged when the car is started the battery goes up to 14 when driving and press brake voltage drops 11-12(car may even die) and to 13+ if u give it gas

Does the vehicle start after sitting over night or do you need to jump start it . Is the charge light on ( batt. symbol ) at any time ? Serpentine belt good , tensioner good ? Battery cable connections good an tight and no corrosion ? Battery also good ? That is normal for battery voltage to jump up to 14 volts after starting , alternator is replenishing the battery after starting ,that draws down the battery . Going down to 11 or 12 volts when stopping and almost stalling isn't a charging system problem . You have a idle problem , IAC - idle air control valve or dirty air passage , a vacuum leak . Giving it gas and it going up to 13+ the alternator is working . Your best bet take it to a qualified repair shop and have it check .

Stalling at low idle

I don't know this specific car. But, if it has one, check your Idle Air Valve. This can cause the engine to stall. If you can hold the gas pedal and the engine will continue to run until you let off the gas, it is likely the IAV. It will not necessarily cause the engine to run rough. That could be a number of things like spark plugs, wires or dirty injectors. It could also be a compression problem. Is the check engine light on?

I would replace the fuel filter, double check your work and make sure that all plug wires are securely connected and going to the right place (we all make mistakes sometimes) and check or replace the coil.

94 cadillac eldorado fuel filter replacement

It could be a fuel problem, but in most cases the rough running would continue at road speed.
You could certainly change the fuel filter and see what happens.
A rough idle but no problems on the road would point to a vac problem or maybe a burnt valve. A fuel or ignition problem would be at most speeds including when you put the engine under a load.
Its possible to have a faulty injector on one cylinder that is bad enough to cause a miss at idle but smooth out on the road, but that is a rare occurance.

1996 Eldorado Emission Light comes on

Depends on what valve they are talking about. The Eldorado is a hard car to get to things. The emmitions control valve is the most probable cause of the light. You should be able to see this on top of the motor it has a tube going to it from the exhaust. You will need a new valve, gasket, and some basic hand tools.
