Hi, I hope you can help me. I think I've read something about my question somewhere, but just can't find it!<img src=/images/forums/snitz/angry.gif width=15 height=15 border=0> Today My Car (1996 Elantra with 56K miles on it) has begun to loose the idle. When ever I'm at a stop, foot aout of throttle, the tach needle goes up to 1500 - 2000 rpm, then goes back again under 1000 rpm, and it even fades like it's going to stop, but then resumes.<img src=/images/forums/snitz/disapprove.gif width=15 height=15 border=0> Also, when I accelerate and take foot off pedal, it remains accelerated for a sec or so, and then goes down to 1300 rpm, and after to secs or so, it goes down to around 800 rpm again.<img src=/images/forums/snitz/mad.gif width=16 height=16 border=0> I'm so dissapointed with this, I hope it's something not too expensive b/c I wanted to spend money on intake and more mods instead on OEM warn pieces.
Please help me figure what's going on.
Thanks

Sounds like the idle needs an adjustment. That shoudn't be too much money. My old Corolla use to do that. Idle too low, then sometimes idle too fast. I brought it in and adjusted the idle and it solved all the problems of whatever it idled at certain times.

Also, you have 56k miles? Get that timing belt changed! (If not already done so).

Thanks jrh382!

I did replace the timing belt (with tensioners also) when the car was about 50K miles. What I need to changte now is the chain on the camshafts, it's making a vibration noise at certain around 2000 rpm - 2500 rpm. I'll take the car to the dealer to have that idle problem solved. It's really great to have the support of HyundaiPerformance.com <img src=/images/forums/snitz/thumbup.gif width=25 height=18 border=0>

Check your idle speed actuator, it might be faulty if it's not providing enough air to the engine when idling, then it feels like it's choking.

HI there guys!!!
Yes friend disconnect the idle speed actuator and clean it real good with carburator cleaner, i used to have the same problem thinking that were the injector, but wrong.... it was the excess accumulated on the idle speed actuator... NOTE. just spray through the holes do not attemp to disassemble it... and also make sure your injectors are clean!!! GOOD LUCK BUDDY!
