Question about 2003 Hyundai Tiburon
Hello. I would say that the RPM sensors are acting up. This intermittent problem can be hard to nail down. If it continues I would have it scanned while driving around and consider replacing the RPM sensors. J.

My sister has one of those sharks too, So I am kind of familiar with it. If the rpms go up and the speed goes down, the problem could be related to the transmission, it could be the transmission speed sensor or shift selenoid.
But, let's start from the bottom, have you had your transmission serviced?? Check fluid level, color and smell. the color should be pinkish and should not smell burnt. If any of this is true, it will be a great time to service your tranny, it is part of the maintenance anyway. Most transmission shops will do a free transmission diagnostic, it won't hurt to have it done.
Once we get this out of the way, will move into something else. Good Luck!! Keep me posted!!

Try replacing the spark plugs and wires, clean the induction system,
and at your next fill-up run a bottle of injector cleaner through it and
see how it helps. Also, it may be time for a timing belt. Thats just a general maintainence item, but an important item.
Secondly, I don't think you're problem lies in the plugs. Hyundai uses a laser-platinum plug that typically lasts a good while.
You could change them and see if it helps, but I kinda doubt it.
Do you have a check engine light on by chance?
The fuel filter is in the tank, therefore a pain in the *** to do. Have to take the fuel pump out and go from there. Don't get into that, its not the problem. I feel you need to service the induction system using a vacuum flush.
As you drive, carbon builds up in the intake, throttle body, and eventually the valves. The vacuum flush runs a highly powerful cleaner through the system and flushes out all the carbon. This frees up sticking valves (which would cause the poor acceleration that you mentioned.) and blows all the gunk out the exhaust. Be very careful about injection cleaning as it can damage the sensors in the motor. The cleaners in detergent gasolines are adequate; higher concentrations can cause damage to sensors.
Keep us updated.

Sorry but they should have driven it straight away ,anyway by the sound of it and what you have described i think the front clutch is worn which will not show up with any code reader ,now also you will not be able to read the codes on this vehicle as YES it has an OBDII under the dash but this is only for the american emmisions test as the diagnostic plug is under the bonnet and its difficult to get the right plug for a diagnostic machine ,later models from 2005 onwards are now using encrypted software and their own diagnostic plug under the bonnet .best advice is take it to dealer let the engine go cold so when they drive it its ok as the parts for the front clutch on an autobox are unavailable as only an exchange gearbox is listed in the parts spares screen ,Best vehicle i can recomend is a ford focus diesel manual ,50mph or a peugeot their very good as well or if funds exist then a VW polo diesel manual .Any of these vehicles will suffice and the money you will save on fuel over 2/3 years will more than compensate plus of course the very high resale value of a small diesel car ,they fetch more after five years than a monster gas guzzler like a merc or porsche .
