2001 Elantra overreving on startup. Anyone else have problem?
 

When I start my 2001 Elantra and it starts on the FIRST CRANK, it winds up
over 2500 rpm.

If I'm careful to crank it for a fraction of a second the first time, then,
when it starts, it only winds out to around 1600 or 1700.

Does anyone else have this problem?

I took it to the dealer twice, but they couldn't replicate it, but they
can't replicate other problems either.

Next time, insist that the service manager come out to the car so YOU
can replicate the problem for him. That way, he can't deny that it exists.

Leave the car overnight with the dealer if necessary.

I'd suspect a misreading throttle position sensor. There were a lot of
problems with these on 2001 and 2002 models.

I had same problem, sensor was replaced, problem persists here and
there. No error code was reported by mechanic. I just rev up engine to
get normal RPM. It is anoying, yet what to do?
(Mechanic had it overnight with no sucess).

sounds to like a auto choke issue maybye??

I noticed that mine does this on occasion, too. It seems to be related
to outside temp and it happens mainly when it's really cold. It revs for
a second or so, then settles right down to a normal idle. I suspect that
this is intentional.

Re: 2001 Elantra overreving on startup. Anyone else have problem?
 

come to think about it, my accent does same thing on startup.
thats completely normal.
even my sis windstar does it.

Re: 2001 Elantra overreving on startup. Anyone else have problem?
 

Hi Jeff,

Exact same problem here on a 2002 Elantra with manual transmission.
I changed the throttle position sensor with no help.
I can normally avoid the engine revving to high by quickly releasing the
clutch just after startup (I always startup the engine in neutral). My
theory is that the engine is having an extra load when the clutch is
released. This extra load slows down a little bit the rpm and, for some
reasons, the computer will finally realize this is idle condition.

By the way, I also find another "anomaly" which is maybe related to
overrevving at startup: when changing gears from 1st to 2nd or from 2nd to
3rd, the engine drops rpm slowly when warm. Does not happen when changing
from 3rd to 4th or 4th to 5th or when the engine is warming up or when the
engine is loaded with AC or rear defroster.

Re: 2001 Elantra overreving on startup. Anyone else have problem?
 

what exactely are you guys considering as over revving?
any new car when started cold will rev high for a min or so .
what rpms are you getting?? like 3000?
our accent doesnt have a tach, but i think its around 1500 or so when 1st
started then slows down to normal after a few mins.

It seems to me that you guys are complaining about the normal operation
of the engine. Mine will spike to ~2500 rpm during a cold start, but it
drops down immediately. Unless yours stays at high RPMs for an extended
time, there's nothing wrong with it.

It's not an anomaly; it's designed that way. This is the throttle
"hover" that enthusiast drivers are constantly complaining about. It
does it in all gears and is actually dependent on RPMs, not the gear
itself. I haven't heard a concrete explanation of whether it's an
emissions reduction method or simply an adjunct to the equally annoying
clutch valve to make stalling less likely in the case of a bad shift,
but it's frustrating to an experienced manual transmission driver, as it
make rev matching more difficult.

Mine will stay at ~2500rpm for more than 10s... it is very long and quite
annoying at night for the neighbors :-(
As explained in previous post, releasing the clutch quickly right after
startup will fix the problem most of the time. When the trick does not work,
I need to quickly put 1st gear and release the clutch a little bit while
using the brakes to load the engine for a short moment. After that, the rpm
drops to a normal ~1500.

I hates this kind of "feature". If someone is afraid to stall the engine,
(s)he should buy automatic transaxle.

why did you buy it then if you dont like how it shifts?
or did you not notice?

10 seconds is long??
what kind of muffler do you have on your car?
it shouldnt be that loud to wake neighbours..

It didn't happen when I bought it. Shifting doesn't have anything to do with it.

That sounds like a real problem. Take it to the dealer and demonstrate
it for the service manager.

Agreed.
