High rev when changing gears and idling i

My 2001 Hyundai elantra is revimg real high rpm's, does this at idle and when changing gears, I can use the clutch to help control this when driving, but when foot is off the clutch it revs at 4000 rpm's. I have changed the tps already and no improvement, cleaned throttle body as well. What could be causing this?

Check your butterfly it may be getting stuck or your plastic housing may be coming in contact with the butterfly. Also check your wire running from your gas pedal to your carborator.at a little wd40

SOURCE: idle at 1500 to 2000 rpm

Most likely the throttle body gasket (between the throttle body and the intake manifold) is leaking.

Change your Thottle positioning Sensor. My 93 lesabre did the same thing and i changed the TPS and it stopped.

SOURCE: High Idle when shifting. It goes up and down idle on it own.

dear friend-the hyundai products has the future of returning to idle slowly so any changes wil not bring it down quicker unless you can find away to confuse the ecu.

SOURCE: high rev problem

this problem I find in alot of 3.4 ltre grand-ams and that is the wiring go to the intake air temp sensor is broken at the connector. the wire will look good but in the insulation it will be broken. just give each wire a tug, if the wire pulls out then that is the broken one.

You are basically describing a vacuum leak that is causing high RPM.If you want to fix the problem look for a vauum hose that has disconnected go aroung at the PCV valve and check for vacuum leaks that are causing high RPM

2001 hyundai elantra idling high


weeeeiiirrdddd. i have a 2001 hyundia elentra gls, and my third cylinder is misfiring as well. my car also revs constantly on idle and in between shifting. it will flutter between 2-3000 or it will just stay at 5000. i replaced my plugs and wires to no fix with my cylinder. autozone also told me that it sounds like my throttle position sensor needs replaced, but every part they try to sell me will not fit and they swear up and down this is the right part...

Engine high rev at stop and slowly goes to idle speed.


I've got Hyundai Lantra 1.6 year 2000. It's take time to start when it's hot. When I start my car it revs at about 2k-3k rpm. It also does it when I come to a stop. When I come to a stop it will stay at a higher rpm than that of idle speed. It drives ok when on freeway but uses more petrol. I have changed the water & petrol pump but no luck

My elantra is rough idling - chugging when I accelerate


I have experienced this. This seems to only happen when its cold out and you use the defrosters/AC. If thats the case then to fix/avoid this you can press the accelerator briefly (while in park/neutral) just to rev up the engine to about 2k or so, before you put it into gear.
