YARNIC.
Yet Another Reason to Not Install a Chip.
$20 says you pull the factory chip back in and problems cease.

No, that _is_ UA. Did you INTEND for the car to accelerate? The term's
meaning doesn't change because of the suit. You just said: "didn't
intend"...

Our Volvo Wagon does this, but only if you're going fairly fast(at least
45mph) and have not breathed on the gas pedal for at least 10-20 seconds;
there is a very sudden kick in the RPMs and you can feel it downshift(not
just sound, slight lurch.) I believe it also happens when you brake to a
stop, but it's very hard to tell.

Sorry, I've NEVER seen this happen on any other OBD-II car...US, European
or Japanese made. The only time I've had lousy gas was when I was with
someone in an older S-10 blazer, and we filled it up at an upstate NY gas
station of slightly sketchy proportions. Blazer had _no_ power as soon as
we filled up...

Certainly; if they find it you can kiss your warantee buuu-bye...how much
of a pain would THAT be? I would also drive the car around a lot before
you go to the dealer, to make sure the problem has dissapeared. Is there a
way to reset those codes? If the dealer sees them, and suspects a chip,
you could still loose your warantee...
