#457 of 720 rough start and idle 99 Kia Sportage

here we go. sounds like many sportage owners are experiencing similar problems to mine...but just a little different. my wife's sportage decided one morning to give her some grief when she tried to start it. all lights, radio, etc. worked and it would turn over but it took a lot of convincing and a little stab of the gas pedal to get started. immediately after releasing the gas pedal it would sputter and die. in order to keep it running she had to keep on the gas. ever since it has given us the same problem. sometimes we are lucky enough that it keeps running but at VERY low rpms, and if you drive it anywhere it will most likely stall out at any stop. it shakes but I think that's just because it is barely staying running. so, we haven't driven it very far at all. taken it to two mechanics. the first cleaned the IAC with carb cleaner and we got about two days out of it and now it does the same thing. the carb cleaner doesn't seem to help as much now. the second changed spark plugs and made sure all cables, coils, compression, etc. were all fine, and they were. they suggested that the timing belt be replaced, but it was replaced at about 50k (we have 75k now) and I refused. with somebody stepping on the gas, I looked down the oil fill and saw everything working like clockwork. didn't check timing but they did, and here's the hitch. after doing a little forum reading, I threw a bottle of fuel injector cleaner in, and wedged the gas pedal so it would stay running. about 15-20 min later (if that), the rpms jumped for a split second then settled back down and the car idled beautifully and ran great the rest of the day. the next day...same thing. I sat in the car and pushed the gas enough to keep it running, and in less than 15 minutes it was like a new car again. i replaced both the main engine and fuel pump relays and it's the same. I am thinking ECM or EGR valve. can anyone help?

now that car sales are way down the car makers like kia sporteage do not need bad press if we all work together and start a campain and write to kia do letter writing to our newspapers let them know that these cars can be a death trap that the auto makers dont care or stand behind there cars I think if we were to set a day all together take our kia sportage to the kia dealers park them with a sigh that says if i want to save a life i leave my kia home this will get press it will hit all the local and national news write to your leaders in your capital put a sign in your yard that says i will pay you to take my car away if you have the guts to buy it send this to your newpaper with a picture and send it to your local kia dealer we need to do this as a team so lets start gettint together and brain storm we can do this we need to do this god bell america .

My 2000 did exactly this! I ended up having to replace the fuel pump, filter and fuel line. Come to find out, the gas I pumped from the gas station had a lot of crud, dirt and sand which clogged the fuel lines. This caused a very rough idle, stalling and would not allow me to drive over 30-40 miles an hour without causing problems. It now rund perfectly and smooth but kinda costly to replace the fuel pump, filter and fuel line.

..." they suggested that the timing belt be replaced, but it was replaced at about 50k (we have 75k now) and I refused. . didn't check timing but they did,"
..well, the only (well, major) factor impacting the timing is... the timing belt.....so, either they did check "both", or they didn't.. SO for me, this issue is not clear.
The other factor is the knock snesor but its impact is minor although noticeable, and it would throw a code.
In fact....you did not mention if you had a code or not....
Sporty engines have a lot of idiosyncrasies....very hard to pinpoint the exact cause for several errances....but at least, you must start with a sound base...and I consider the Tbelt as a definite suspect to be cleared safe and sure, and then you can continue without any doubt lingering behind. I suggest you pay a visit ; ajustment of the tensioner is critical and it is possible the belt can jump a cog or two.

lmp4. I apologize for my lack of understanding on the timing issue, as you can tell my experience is very limited. I guess my overall question in response, though, is that if the timing belt needs to be replaced would it be normal for the car to run so perfectly after a long warming period? it will run at any speed, restart fine, and is very responsive, like a new car. if it sits overnight I am back at square one. thanks for getting back to me. I will report back with codes.

"the car ..runs ..perfectly after a long warming period.. .. if it sits overnight I am back at square one"
OK..this contradicts the Tbelt issue, indeed. Was a fuel pressure test conducted?

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.
