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)

SOURCE: 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.

My 2003 Hyundai tiburon gt v6 (automatic) idles at 500 rpm in drive after warmed up is this normal? It's not throwing codes it just feels like it's shaking a bit


500 is too low for and automatic in drive
normal idle is 850-900 and should not drop below 800 in drive as the ECM should be adjusting for the drive load when in gear
take it in to an accredited service shop that works on your make of vehicle and have the problem diagnosed properly and quote

My 2003 hyundai tiburon 2L iddles at a steady 4000 rpm and wont iddle down. How do I fix this??


There r 2 cables on a gt 6 speed that r located at the top of the engine in back.. Do not touch the rear cable unless ur tibrron is shifted hard. The front cable is ur drift idle, theyre 2 nuts tightend den to secure it at a certian level , untighten the nuts and simply ajust the 2 nuts backwards do the cable isnt so tight and allows the engine to drop idle wen accelerater isnt pressed. Then do the same to the rear cable(2nd) cable untill u have ur tibron sounding just right..only sol_tion

Hello I have a Hyundai tiburon 2003 v6 GT. I don't


the rpm's can vary from car to car , it all depends on the gearing in the transmission and ratios, 4.0 does seem high for a V6 the easiest thing would to be have your transmission serviced , on this car you need to get the Idle Air Control checked, In all the forums Ive read on this car , that seems to be whats wrong when the RPM's seem to high, also if you have the automatic trans and an electronic manual shifting mode does it do the same thing when you have it in the manual mode? there has been lots of discussion also on the MAP sensor,, I would suggest you have the OBD codes read to see if its listing any trouble codes within the computer that can help with locating your answers, once you get those codes if you post the results here, people will help you and explain what they mean, If you reply to this feed by replying, I will look them up for you

My 2003 Tiburon GT V6 5spd has been intermittantly hestitating and missing while at a contant speed and even stalling out from time to time. Also, the engine revs high at 2000 rpm then back down to 1000...


have you changed your fuel filter in the last year or so, if not. do it. a plugged up fuel filter will cause a lot of issues also. it can cause stalls, hesitation and stumbling.

RPMs drop


spark pug gaps are critically important & can even stop a car from starting! start there!
then reset the timing!
computorised cars should be banned! lol

2003 Tiburon GT Remote Key


Seriously don't use the factory alarm system / keyless entry.

While my car was under warranty, the alarm malfunctioned and it wouldn't disarm. The solution was to have the car towed to a dealership and install a new BCM. This would have cost me over $1,000 - and it's not an isolated case.

Don't get a Hyundai key fob. Have an after market alarm / keyless entry installed. It will be cheaper & easier.
