touchy gas pedal

Hello all, I have a 04 Sante Fe with the 3.5 V6 and 44,000 miles. In the
past few months, the car has developed a peculiar problem. At times, when
moderately accelerating from a stop, the car will take off like I've put my
put my foot into it. The gas pedal seems very touchy. I brought it to
Hyundai and they said it could probably be carbon build up in the throttle
body. They wanted $120 bucks to clean it. I turned down the offer. Has
anyone run into this before? And if so, what was done to fix the problem?

Thanks,
Derek...

 

Drive-by-wire throttle. Try this: disconnect battery terminals which
will reset the computer to default values. The computer will "learn"
again your style of driving and it should (hopefully) remedy the
problem. If it doesn't it cost you absolutely nothing to try. It
helped when my Hyundai was shifting poorly. The computer re-learned
how to shift after above process.

 

This happened to me & it was my cruise control kicking in when I
accientally hit the RESUME button on the side of the steer wheel. The
car went into 35 as I was doing.

 

Derek, Try this. Im kinda stealing Hyundaitechs fire here but this is what
he told me when I had that problem.

Turn your key on BUT DO NOT START CAR leave it on for about 10 - 15 seconds
Then shut it off and then start car, it resets something ( I forget what )
but it worked for me !!

P.S. If I was wrong, HT please corect me. I was wrong once !!! And it took
me 10 years to get rid of her.

 

Just turn on and immediately back off. If you wait more than ten seconds,
it won't run the throttle sweep.

 

Do you have to move the throttle or just turn the ignition on and then
back off?

Thanks,
Matt

 

Hmmmmm guess I did mine wrong, but it did do something and the problem went
away.... See what happens when you get old ?? you cant remember from the
computer to the car...In my case 20 feet or 20 seconds whichever comes
first.

It’s possible the throttle needs to be reinitialized. Turn the key to
the on position (don’t start the car) and immediately back off. The
throttle plate will complete a sweep and should be initialized within
ten seconds.

If this doesn’t resolve the issue, it’s possible that an available
reprogram will help. Technical service bulletin 04-36-012 lists a
reprogram available to provide "smoother feeling initial
acceleration."

 

Nope. Don't touch the throttle. Just cycle the key. Although you've got
a different system, Matt, your car uses the same procedure.

 

Thanks, I'll give it a shot.
