The 3.5 has an electronic throttle. Depressing the accelerator simply
activates a sensor under the hood. The computer controls everything from
there. It'll probably take a little time to become familiar with its
idosyncracies.

As for the fuel economy, I don't know that it will improve. We've had
many complaints about fuel economy on the 3.5 Santa Fes. I've never been
able to find anything conclusively wrong with any of them. I replaced an
oxygen sensor in one of them because the values looked a little funny, but
the customer was still getting poor fuel economy.

I also do not know whether fuel economy will improve.

This I do know - that powertrain combo is used in some other Hyundais and
Kias. It is a nice, smooth and responsive powertrain, and seems to be able
to handle whatever is given it. It also seems to have given VERY few
problems in its years of operation (since about '01 or '02).

But one thing this powertrain has never been is very fuel efficient. I've
had this powertrain combo in two different vehicles - one was an '02, and
now I have an '04. The '04 is decidedly better than the '02, and I love it
in my vehicle. But I will never jump for joy over its fuel economy.

But I will gladly keep running it and running it and running it - as long as
I keep the timing belt replaced. It is one of the most impressive
powertrains I have ever had.

I experienced something a bit different from the way you are describing it
with my 2005 3.5L Santa Fe.

The car would either hesitate when the gas was depressed or surge as if I
had tromped on it. The dealer reprogrammed the ETCS and this fixed it. I
believe these is a TSB out for the problem as well.

Could that be what you are experiencing?

It's more mechanical in nature (and yes, I realize its an electronic
accelerator). The problem is that the pedel is very "stiff" (for lack
of a better word) when I first begin to apply pressure to it with my
foot. Rather than giving way gradually and smoothly, it "breaks" in
that it just suddenly gives way. As a result, acceleration is also
sudden and jerky from a dead stop. I can overcome it with effort by
stiffening my foot and ankle muscles so that the pressure I apply is
even and compensates for the sudden give by the pedel.
