2003 Hyundai Tiburon GT randomly drops RPMs

The only happens every once in a while, but when it does it nearly kills the engine. Whether the car is idling or driving, the engine sounds like it cuts off for a second and drops anywhere from 500 to 2000 RPMs.

Drops anywhere from 500 to 2000 RPMs. ??? don't understand what you're trying to describe. First suspicion - throttle position sensor. Go to http://www.hmaservice.com/ and register (vehicle by VIN). Afterward, you'll have access to technical information (manuals, wiring diagrams, service bulletins, etc) about your vehicle.
If you don't want to do this, then I recommend you take/tow the vehicle into a Hyundai Service Center (dealership), pay the diagnostic fee. They will tell you EXACTLY what the problem is and what's needed to fix it (parts, labor, tax, time-frame, etc.).

IS it a stick or auto shift?. If it an auto shift it sounds like a bad map sensor. It is mounted in the air intake system. Any check engine light when this happens?

I have a 2003 Hyundai Tiburon Gt.When im coming to a stop and Im in neutral my car idles high.I can rev it up it drops back down to a 1,000 rpm's or where it should idle at.


Hello
The engine and transmission in this cars drivetrain are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s)

2003 Tiburon GT, RPM's drop way down and idles rough at stop's?


More maintenance history needed. Oil changed regularly, timing belt replaced at 60 K miles, Engine air filter & intake air hose inspection?
Causes of the problem you describe are many. Recommend you have a technician check your throttle position sensor for any bad spots in the potentiometer... most likely cause when there is NO Check Engine light.
