to anyone taking the time to read this, Thanks for your time, I appreciate it.

Now on to business:

My 2004 Santa fe seems to have a particularly interesting issue. When I drive, it will spontaneously die as I'm driving down the road, or start to "stall." I'm not a mech-head so I don't know what the correct terminology is.

Basically, if I have to give it gas, most of the time it will do fine, but there are times where it wont increase accelleration, it will definitely stall, or sputter (causing a slight jerk) or it wont go up a hill, even when I pressing down 100% capacity on the accelerator. If I'm maintain a constant MPH, it will all of a sudden start to choke, and almost die, but then go back to normal. Sometimes, I can't get the car to start altogether, as the motor will kick on, the starter will definitely crank, but the starter just kicks, and nothing happens. If I wait a couple seconds, then try again, it'll start immediately.

Now, I checked the alternator, its fine. The battery is fine. the starter is fine. So the next thing I'm thinking is the fuel system. I figure its gotta be something with either the fuel injector system, the fuel pump, the fuel lines, or even the filter. Any ideas, or suggestions are welcome.

Also, I know my earlier explanation may not have all the necessary information you guys may need, so please feel free to ask any questions and I'll definitely answer them right away.

I also recognize and welcome any additional advice on whether it could be something outside of the system, such as the sparkplugs or some such. I do know that the coil pack was just recently replaced a year ago, though.

She only has 75,000 miles on it.

Thanks guys! Appreciate any help you can give.

I would check the Fuel filter then if it's good check the fuel pressure with a gauge. should be a constant 40 psi..about.. leaning toward filter because it runs good most of the time.. Good luck.
