This topic has come up several time recently at kia-forums.com.

While attempting to accelerate, the engine may drop back down to idle
speed for up to twenty seconds. This has been reported on both diesel
and gasoline models and both on automatic and manual models. The
problem, so far, corrects itself. But, while it's happening, dangerous
situations can occur.

Just a heads up to my fellow Sedona owners.

Funny; we blew a mass air flow sensor this past weekend when I tried to
pass a semi.

Luckily we were able to get it off the road without mishap.

Friggin computers. Damned things attempt to run everything and f.ck it up
royally more often than not.

Glad you came out of that with no problem.

Computers are just way too complex not to be buggy. And, if we were
ever to work out all of the problems, we would just add new
functionality that would, inevitably, screw up.

Very interesting, thanks for the link, CMM.

I haven't noticed this at all (60K miles on my '02) but imagine that it
could happen due to various issues.

My only response would be to possibly downshift to force the
accelleration. The OP might also have the ECM read just to see if there's
any codes being thrown which aren't enough to cause the Check Engine
light to come one.

Wierd. As one who does mostly freeway (80+) driving in the car, I haven't
seen this but would be leery of needing to pass. Maybe because he's in
England - and they drive backwards there - the engine didn't know what to
do. :P

Wo ist der Ort für den ehrlichsten Kuss
Ich weiss, dass ich ihn für uns finden muss
Auf 'ner Strasse im Regen, auf 'nem Berg nah beim Mond
Oder kann man ihn nur vom Totenbett holen

Those backward, diesel engines over there are a lot different than
ours. I guess, even though the problem exhibits itself in the same
way, the cause may be totally different.

Unfortunately, though, it's happened to some US drivers, too,
including me. I was starting up from a stop light. Let off the brake
and pressed the accelerator and it just crawled across the
intersection. I had some cars behind me so I pulled off to the side
and let them pass. Tried again. No problem. Made a turn about a mile
up the road, went to speed up again and same thing. It happened to my
wife once before that and once after but the problem hasn't recurred
in several weeks.
