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.

Car running rough after it sits over night


Your Idle Air Control Valve has gotton Carbon Build Up and needs to be cleaned. 75% of the time, you can clean them and they will work immediately but 25% of the time, you have to replace them but the IAC (Idle Air Control Valve) is the same as a CHOKE on older cars... and it is just not adjusting the Fuel/Air Mixture correctly

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)

After cleaning the throttle body it looks to be stuck and RPM remain above 2000 when idling. Engine accelerates and decelerates going back to idling at about or above 2000 RPM.


When you cleaned the throttle body, did you remove the Idle Air Control valve/motor (IAC)? A dirty or defective IAC can be the result of your problems. The IOAC regulates your vehicles idling under various condictions. Try cleaning it first then replace if needed.

Please remeber to rate this solution. Thanks!

When started idles between 2500 to 3000, have toshut t off and restart


usually its the idle air control motor causeing this. take it off and clean it out.(iac). when cleaning do not push valve in thats on the end, the best to clean is an old tooth brush or similar.this should help idleing. it may be sticking. this valve replaces the fast idle on older cars.this makes it idle at a proper rpm.

Under 2000 rpms runs bad/hesitates/check engine light


This IAC valve runs only when your foot is off the gas pedal. Mainly to keep the engine from stalling and keeping it at a safe RPM. If it is running bad under 2000RPM, more than likely its the IAC valve or a vacuum leak. Clean or replace the IAC valve....Hopefully this helps!!
