2000 Kia Sephia

Drain fuel tank and replace with fresh fuel from a different source. Then request the original fuel supplier to cough up and pay for the tank of dirty fuel (probably contaminated with water) and new filter. Or buy can of fuel cleaner and pour into your car's fuel tank.

Cheers, Peter.

Sounds like bad gas - particularly water in the gas. Auto supply stores sell products to add to the tank - alcohol of various sorts, isopropyl being the best - to correct that. My guess is that the water stayed in suspension well enough until you parked the car, then it settled to the bottom of the tank and got picked up with the fuel.

while you're thinking about fuel, consider possibility that the fuel pump might be failing. I've been thru that twice now with my 89' 240, the most recent being this past week! Unexpectedly left me stranded on the side of a busy road, started and ran fine for an hour or so before that, so no warning. Replacing the main pump solved the problem, and the car actually seems to have a little more pep than I remember from the last few weeks, so perhaps that was my warning! I think the in-tank pump is ok (replaced with the main pump last time around), but will replace it too, when we get a little warmer weather here in Atlanta...

Always a possibility, although in more recent cars with OBD II fuel pump weakness should bring in the "check engine" light as the mixture won't stay good.

Trade it in for a used 850!

Ok if that is not in the cards buy 2 or 3 bottles of 'dry gas' and put one in the tank now with no additional fuel added--run the gas down to 1/8 tank, then pour the 2 remaining bottles of dry gas in and fill with quality fuel of the usual octane (ie regular no advantage to using high octane)

Happy motoring!

Oh gheez. um - it could be nearly anything with a KIA and that many miles. My guess would be the MAF or something simmilar is shot. If the car has an EGR valve, that is also a place to look. Sometimes both die at once. Well, one is dead already and the other dies. The computers can no longer compensate.

I'd take it to the dealer and use that 10 year warranty.
