Hi, I hope you can help me (I also posted on Maintenance, I'm almost desperate). I think I've read something about my question somewhere, but just can't find it! Today My Car (1996 Elantra with 56K miles on it) has begun to loose the idle. When ever I'm at a stop, foot off 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/evil.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. It's annoying to drive like that <img src=/images/forums/snitz/disapprove.gif width=15 height=15 border=0> 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. At the dealership they told me they have to take a close look at it, but it seems to me that means big bucks. <img src=/images/forums/snitz/angry.gif width=15 height=15 border=0> Please help me figure what's going on.
Thanks

Looks like you have a throttle sensor problem, Try this, Disconnect your negative battery terminal for about 15 minutes, this resets everything, then reconnect it and take it out for a test drive, If the problem continues you have a bad sensor, get it replaced.

You think so Lantra? I had a similar problem with my old Corolla. The idle would be low and then when I would stop, it would jump up, then drop back down. I had it adjusted by a mechanic and it was fine. He didn't say it was sensor problem. Just needed an adjustment because the car was old.

And as I said in the maintnace forum....Get that timing belt changed! If you haven't already done so.

Yeah, he probably just needs to do that or have a throttle adjustment, the throttle controls air/fuel into the motor.

is it snowing there? I've had problems with the throttle cable getting to tight, the idle adjustment and the butterfly valve getting ice stopping it from closing, and do check the TPS with a multi meter to see it it gets, +5, ) and .5 to 4.5 v while you open/close the throttle.

Thanks for the advise. It's not snowing here in Lima (Peru), our wether varies from 12°C in winter to 30°C (that's 53°F to 86°F). The thing is our humidity range varies from 85% to 99% all the time. Anyways, I'll check the throttle cable, because it could be stucked, dirty or not with enough lube on it. Thanks Brendan.
