I have a 1999 kia sportage 4WD with the exact same problem and circumstances. It won't start cold unless I hook up a battery charger, and crank it for 8 minutes with the gas pedal nailed to the floor. After sputtering, it begins to run...then runs perfect. It will start again for the rest of the day, and run well. The next day....same problem!!
I replaced the timing belt, and water pump. I installed a new radiator. I replaced the spark plugs. I replaced the the coolant temperature sensor. I am getting a code that my oxygen sensor is bad.
Did you check your fuel pressure, as you were asked? Have you solved your problem? I have spent a good deal of cash replacing the wrong parts, and still can not cold start this car!!! -Thomas-

the first mechanic I took it to wrote down codes "CTS" and "AIC." I don't know if these make any sense at all. haven't bought a code reader or had the guts to take it to a shop again. a fuel pressure test was conducted by the second mechanic and everything checked out fine. but since the car does really well for me after warming up for about 15 to 20 minutes, I wonder if they were dealing with a seemingly perfect car after it had sat in a warm/dry garage for a while. here is the latest development. I live in southeast alaska, where the winters go something like this...we get a lot of rain on snow, snow, then more snow, then rain on snow, then sleet, then rain, then snow snow snow. as you can imagine it is a pretty messy time of year. over the last few days we've had a cold snap out of the ordinary with no precip. for us, something amazing happens when the weather is like this...things dry up with the extreme cold. the last few days have probably been the driest we'll have all winter. anyway, our first cold snap day the car was miraculously cured and has been ever since. NO start up problem every day for the last 4 days. I spent the weekend checking everything electrical connection and wire I could reach. everything on this car looks brand new. then I thought, shouldn't an electrical problem be WORSE in the cold? maybe unless it is due to moisture? she drove it to work this morning and it is fine. supposed to warm a little and dump more precip, we'll see what happens.

CTS is the Coolant Temperature Sensor. I bought one, and installed it. It cost $21.00, and was easily installed,(located in the front of the engine on the thermostat housing). Only neede to loosen 2 bolts holding down the plastic air duct on top of the radiator. The car starts cold now, with only minimal effort...still not as good as warm.
I don't know the other "AIC" code, but a Parts person at a local Auto Parts store should know what it is. Thank you for responding.

..makes sense...a shorted coolant temp sensor (either internal short or externally caused by moisture) looks like a high temperature condition...so the computer thinks the engine is already hot..and keeps a lean mixture, hence very hard starting and low idle....until the engine is actually warm and matches the computer thinkink.
.....and that would probably translate into a poor O2 reading, probably lean.
...AIC...may be mispelled for IAC.....Idle AIr CONtrol valve.....would make sense too....frequently the culprit with difficult starting.... I think you said you had it cleaned....but check electrical contacts to that part...and may be its real condition..

well when it rains (or snows) it pours. now the 4 wheel drive on my toyota is out so I haven't ahda chance to look at the kia. anyway, thanks for the reply and I'll see if this helps. the code must have been IAC like your said, because the mechanic wrote "air idle control." I spoke to the mechanic that I took my truck to, which is now our 3rd try at a mechanic inthis town, said the IAC was a likely culprit too, and that's what the code must be. the car is still running fine for now. I'll get in there and look at the wiring to the CTS (and IAC again). maybe change the CTS since it's cheap and sounds easy. or should I wait to change the CTS until the car acts up again? hard to troubleshoot when the car's running fine.

Great site thanks for the link

Tim, Did you get this resolved? What worked? I have the exact same problem. 2002 Kia Sportage rear driver's side electric window will go down with either driver's or pasenger's switch. However, it will not go up.
#471 of 707 tune up made it run bad
Feb 08, 2009 (9:44 am)
my 2000 kia was running a little rough spitting and sputtering while taking off. the shop said replace coils wires and plugs, i did that put it all back together and know it runs 50x worse than it ever has. i then put all the old stuff back on and still runs worse then i did every combination of old and new parts still nothing. it is also getting the exhaust from the manifold to the converter red hot. so i took the converter off and put a temp. flex pipe in its place but it all still gets red hot. i am lost, all i did was a basic tune up and know i cant even drive it. any help?

Red hot exhaust is a sign of lean mixture...in which case you should have the check engine light ON..... is it ? The cause of this ..and possibly of the trouble you wanted to solve , can be a false reading from O2 sensor...there are 2, one just at manifold , the other after the first cat....

it turned out that i had two plug wires crossed. 3 hours of guess work and a good nights sleep i finally figured it out. thanks
