I have a 2003 Ford Taurus ses.
Recently I went to leave my house and when I started my car, my rpms were really low, at about 500 to 600 rpms. It felt like it was jerking and jumping around. I put it in reverse and was able to back up and leave my street until it died.

I noticed when I was driving at higher rpm's, I didn't feel the shaking or the jerking until my rpm's got down to around 2000. I made it like 1 quarter of a mile and it died on me. I tried to start the car, but it would just crank over. I thought it may be the gas, because I was really low on gas, so I went to get some. Put about 7 bucks in gas in it and tried to start it.
The only way it would start is if I gave it gas, but even when it gave it gas, it still clanked and shutter. It does sound like there is a clanking noise.
My sister who was looking under the hood said that EVERYTHING in my car was just shaking violently.
About a few months back, it started dying on me at odd moments. So I had a friend of mine look at it a few days ago and we could hear a small hiss noise, like a vacuum leak.

So if you were facing the car with the hood up, the hissing noise comes from the right side all the way in the back, just under the hood. Sort of like behind my transmission.

I am a college student and can not afford a mechanic right now, I am extremely upset because I keep having awful problems with this car. I need it to get to school and such.
If you have any idea, please, let me know. I may be able to make a video of it and post it on here later.

P.S. it is a automatic

Hello Paula,

The only thing that I can think of that would "hiss" is the brake booster vacuum supply line. Since the vehicle may have run out of gas I would suggest turning the key on and off about 5-6 times to get fuel pressure back into the lines.

Let me know if you find anything.

Troy. :)

So, I went back and tried to start my car and it started on the first try. So is has to have to do with the fuel
Could it be the fuel pressure regulator? If so, where is this located. English please? Lol

Don't run your Taurus or any other modern car low on gas, below 1/4 tank or so. I don't care how many times you and people you know have done it and gotten away with it. Don't. When an electric fuel pump runs dry, it overheats and destroys itself. The fuel is used to cool the motor as it passes through the pump. No gas=siezed electric motor=$500 for fuel pump replacement.
