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

RPM's drop way down and idles rough at stop's? No engine light just this rough running. Did this once before about a month ago but only did it for few minutes.

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

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)

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.
