Question about 2001 Hyundai Elantra
My 2001 hyandai elantra idles high when started and when shifting gears.i stopped driving it becuse it tacks out so high.check engine light is on.auto zone said it was a misfire on the third cylinder but new plugs and wires didnt work.
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...

I had the same problem, turns out it was a bad gasket where the intake enters the block, i found the ."hole" and plugged it with some silicone

I have a hyundai elantra 2001 and the rpm goes up high when I turn on the car. It also stays high while driving at some point it will go down and the car jerks into another gear.....I have replaced the throttle position sensor, input/output speed sensor, the IAC, checked the valcum holes for any leaks and I'm still having this problem. The check engine light stays on all the time because of this on going problem. Please help I've done spent a lot of money and my problem still is not fixed.

Its the intake manifold gasket. I have an 01 elentra that did the same thing and I replaced that and now it runs perfect.
