The car starts fine, but it won't stay running independently. As soon as I stop revving, either in neutral, park or drive, the car dies. I would like to know what the problem could be so the mechanics don't take me for a ride by telling me I need a new engine or something equally outlandish just because I am a female and don't know any better.
My car is an automatic Nissan Pintara from 1985.

it could be a pile of things, but some of them are: There's a vacuum leak, or your fuel filter(s) need to be changed(I'd check that first...especially if you have no idea the last time they were). The question I've got for you is: have you tried to put E85 in it? If so, it'll run just like that. If you have, you shouldn't have caused too much damage, but if it doesn't clear up after a tankful of normal gas is run through, you may need some gaskets replaced in the carb. Another thing to check is your air filter...you can do that yourself- just take the filter canister apart, and pull the filter out. If it's visibly dirty, and if when you shake it dirt, bugs, and grass comes out...maybe you should spend a few bucks and put a new one in. You actually should change your air filter and fuel filter on a yearly basis...mainly just to keep your engine running as effeciently as possible. Hope this helps!

This sounds most like a EGR (exhaust gas recirculation) valve stuck open. When this happens too many exhaust gasses are in the combustion cycle at low speeds or low idle.
Little pieces of carbon break loose in the intake manifold passages or fall off the fuel injectors and lodge in the EGR valve.
They can clean it and re-install it but it will likely happen again in the future. There's lots more carbon chunks in there somewhere.
Sometimes the throat of the EGR valve is worn from age and has to be replaced. The car will run without an EGR valve but it has to be or stay closed so no gasses are introduced into the combustion cycle. You most likely have a small vacuum line that is connected to it and you can pull this off and plug/cap the vacuum line aftere they knock the carbon out of it.
They may check the fuel pressure and throttle position sensor as well if they can keep it running to do a engine diagnostic but my guess is that they'll stop if they recognize it as a EGR valve problem.
The function of the EGR valve is to prevent some engine knock from low octane gasoline and is part of the emissions system.
Good Luck!

Does the engine smoke when you start it? Chock stuck open, Idle speed set wrong, Cab. jets clogged, Fuel/Air mixture set wrong, all the above mean a Carburetor rebuilt or new Carburetor.

whether that's revving no longer in user-friendly terms putting at a stronger rpms..it can be a caught gas injector..the two that or that's a honda..that's gay. thank you to waste good money on the intake and exhaust to make slightly poop sound somewhat extra efficient.
