How to up MILEAGE ON HYUNDAI???

Thanks for that suggestion,
I have a other problem with my doors, there open and close
automatically, not on my command, but when ever there feel to.
Sometimes 30 times in a row, I open them and there clos again.
Or the other way around I close, their open!
Luckily not when I'm driving.
So resetting the ECU would maybe cure this problem to.
On the other hand next week I have a appointment by the
dealer for this problem, the second time. The first time their
did something, don't know what, but anyway it did not help.
Thanks again, sometimes the solution to the problem is very simple,
maybe I get lucky.

 

Are you sure its not due to some ghost in your car?

 

My wife uses the car for work. She's a private conveyor for school
children.So the car is driven a lot. The tires were replaced because of the
premature wearing of the ball joints. Second time because of a rim problem
that wore them unevenly. ( the car vibrated at about 60mph.) They replaced
rims and tires. It worked. Maybe it is a Canada thing. All of the listed
items were dealer repaired under warranty. Which is a very good thing. I
wish they would clear up the 2-3 upshift flare, I really want a sonata when
I trade in, but im afraid to take the risk

I was thinking about that to, as far as I know
there is a Ghost in my car (little green one), but he has no drivers
licence.
So its not him.

 

Glad to hear that.

That seems to be the case, at least based on what I've seen and heard.

You could always get a car with a manual transmission. ;-)

 

But then you can't get the leather interior and that nifty
electrochromatic mirror (I love this thing, never buying another car
without it).

 

You don't gain anything by doing that.

 

Actually, you do. The stock intake (at least on the '04) pulls warm air
from the engine compartment behind the radiator. Removing the resonator
and the "snorkel" results in the intake pulling cooler air from inside
the fender, which is fed by the openings around the fog light. Call it a
poor man's cold air intake. Aftermarket CAI's route air from the same
location.

Besides, the 5 or 6 pounds you remove makes HUGE difference in
accelleration! ;-)

A similarly inexpensive modification involves bypassing the coolant
passage that heats the throttle body. While warming the incoming air can
be useful in the winter, it reduces air density and horsepower in warm
weather.

 

Do you know what part of your car measures the quantity of intake air?

 

Of course. On the '04, it's the MAF that's located between the throttle
body and the filter box.

If you're implying that removing the resonator will impact the MAF
function, you're wrong. The resonator is downstream of the MAF and
filter box.

 

There is a second resonator between the MAF and the TB. That one
doesn't do anything. As was said, removing the first resonator can
make a difference.

 

ok, we're talking about 04 Elantra, right? could you point me out what part
did you remove in this drawing?

Right, there's one on the "elbow" of the pipe connecting the throttle
body and the MAF. I'm curious about it's function. I hope it's strictly
noise suppression, since that pipe will be replaced once I find a CAI
that will provide better flow than stock without compromising filtration
quality.

 

What I removed is everything downstream of part# 28210. That includes
the resonator/flex pipe assembly #28210f and it's snorkel-like extension
# 28214g.

 

It should be pointed out that a 100 000k in Canada is just than.. Kilometers
is the K thing in Canada.. Which would be right around 63000 miles..

Actually it's 62,137.1 miles, but who's counting?

 

That woudn't make any difference. I've measured the temperatures around the
inlets a couple of thousand times so far on my test mule.
