There can be a few things to look at. A vacuum leak. The idle air control valve or a problem with the transmission. is there any codes?

    The transmission is slipping a little. No codes are showing on the dash if that's what you mean. Not sure what your asking when you say are there any codes.

SOURCE: 99 HYUNDAI SONATA, ENGINE WHEN WARM CONTINOUSLY REVS

Sme thing happened to me, but the advice is grim. I had to have the whole transmission replaced because of a bad torque converter...I would be sitting at a light and the car would just go all by itself, or as I was driving down the highway the tach. would go crazy and shut the car down into "safe" mode where it would not go out of first gear. Other times I would have to keep both feet on the brakes because the car would be pulling so hard! The dealership told me the crankshaft position sensor too, then a month later the car just shut down and would not start. Hope this helps.

My Son's 01 Sonata displayed the exact same systems and it was his catalytic converter. The metallic sounds were the converter guts disintegrating.

THERE IS A TEMPERATURE SENSOR ON MOTOR WHICH CAUSES THIS PROBLEM... USUALLY IT SHOWS A NEGATIVE TEMP READING WHICH CONFUSES THE COMPUTER CAUSING IT TO REV UP....HAVE THE ENGINE DIAGNOSED ON A SCANNER....GOOD LUCK...

MY 1987 CHEVY MONTE CARLO LS ENGINE RACES WHEN START IT UP.IT WON'T STOP TILL, MAYBE 7 0R 8 MINUTES


Two places to start. First clean the throttle body/carb. Brake clean and a tooth brush. Clean inside as best and deep as you can, clean the back of the throttle plate and were it seats the most. It will take a few seconds, start the car up and spray the cleaner in the throttle as you rev it up. Then after that, I would replace the engine coolant sensor.

Whining noise at low speed


If the noise happens when car is in park and you rev it to about 1500rpm's then its thebearing in the oil pump of the torque converter.It should make noise all the time even in park ideling. You may need a rebuild transmission. Have the vehicle checked out at a transmission repair shop

Noise when driving starts from 30 mph.. when turn wheel to left on the interstate, the noise becomes louder. Change left axle the noice didn't go away... also leaks around the axles, and from power...


sounds like powersteering pump. put it in park and open hood. have someone stand in front of engine near powersteering pump and put hand on it to feel vibration. MAKE SURE CAR IS IN PARK. Rev engine to about 2200 Rpm's and see if I am correct. Thanks and Good luck
