My car I got for Christmas is messed up?

We dont have much info, it is green, so that explains everything.

It's a hyundai. You press the accellerator down hard and the engine dies.

Not much to go on.

Very lean condition? adding more air with throttle wide open?

That could die, or cough, at a low speed.

You need someone to verify and define the problem gathering the data, the vehicle info, then update your question.

a car that costs 2000 is probably several years old, we do not know if the filters and maintenance are up to date and we dont know the mileage. We need the trouble code if it can be read.

If you can drive it without flooring it is it ok?

You might get it looked at and take the tech for a road test to demonstrate and gather clues about other symptoms that may exist, get it inspected immediately to find out what you bought and its present and upcomming needs.

Give the car back, you need to take some lessons first.

Examples

It's not gas, its gasoline. Gas is like air. Gasoline is a fuel.

It's not peddle, it's pedal. To peddle is to sell - like pedlars.

It's not a gas peddle, it's the accelerator or throttle.

For info, if you suddenly "put the pedal to the metal", a lot of cars will hesitate or die because they need a service and proper adjustment, which current and possibly previous owners may not have done.

There's gratitude for you, you've been bought a car and already you are finding fault.

Why are you pressing the gas pedal hard? That's a sure way to mess it up.

Start it and let it tick over at about 1000 rpm until it's warmed up. There is no need to hit the pedal hard, even when driving, that's why you have a gearbox.

"when I press on the gas hard"

Learn how to drive WITHOUT pressing on the gas hard.

OR, if you don't like that car very much, you just go down to a nearby dealer and trade it in on a brand new Corvette.

What, you don't have enough money for that? I guess you better be happy with the free gift as given and STFU.

Anything can be fixed. A $2000 car is not going to be perfect. If your car randomly dies on you, then it's a safety hazard and needs to be fixed. You need to be talking to your parents about it, not fishing for random opinions here.

It's gas "pedal", not peddle.

If you are flooring the gas pedal while in neutral the computer will shut down the revs once over 4,000 rpm to keep people from blowing up their motor. If it stalls while driving and flooring it you have a motor problem that may be tune up related or perhaps a timing issue. Go find a mechanic with a scan tool so they can read the engine data and see if all the senors are in spec.

The previous owners might have taken it to a repair shop and found out it isn't worth fixing and decided to sell it. It is why trained mechanics or techs call it troubleshooting. Have patience and find an A.S.E. trained professional to help, do you like the car keep it if not get rid of it as it is yours to do with what you want.

The most common cause of an engine killing when you hit the gas pedal, is a clogged fuel filter that causes the fuel pressure to drop. But it could also be the purge valve, EGR, or fuel return pressure regulator. You need to put a pressure gauge on the fuel rail and see what happens when you try to hit the gas pedal.

If you are revving the car hard while it isn't moving, you are probably flooding the engine - which would explain why it is cutting off. Learn to use the car properly before complaining that it is faulty.

You're flooding it, stop pressing on the gas hard.
