Hi,Having problems with my 98 Kia Sportage Sedan with high revving .I took it to a Kia dealer but they couldn't find anything wrong with my car,tested motor,throttle cable and sensor light but nothing seems to be wrong with them???It's doesn't happen all the time it's only happened about 5 times over a 2 week period it's unpredictable you don't know when it's going to happen.A couple times it happen first thing in the morning and just revs right out like it's going to blow up and that's with know pressure on the gas pedal,and other times it's happen in the afternoon,same thing it did back fire once only.There know warning lights coming on the dash.Could it be a knock sensor switch.Or bad fuel.Any ideas it scares me to drive my car dont know if its going to get stuck on full the gas pedal and i have a crash!!!PLEASE!!!! :-(

SOURCE: 2005 Kia Sportage kills when release of gas pedal

Sounds like a faulty engine warning light and a problem with one of your vacuum hoses. This is difficult to find. Probable just an old cracked hose or loose connection. Propose this to your dealer. Just keep taking it back and tell them to check all of the vacuum hoses and the computer. Good Luck

SOURCE: 2005 KIA Sportage Engine Warning Light and Misfire Problem

Engine check light comes on - defect of a range of Sportages - manufacturer should repair it. Check the recalls on Kia Sportage. My vehicle had to get an entirely new engine. This is after the vehicle refused eventually to start.

SOURCE: 2001 Kia Sportage randomly stalls

It sounds like you have a fuel pump issue. when the fuel pump fails you will not usually get a code, all the things you have replaced so far should have been lead to by a code. It is not usually a good idea to guess at automotive repairs. The next time it stalls, listen carefully to see if you can hear the fuel pump running.

SOURCE: 2000 kia sportage ex won't idle

Need a repair shop to diagnose it

You never should have thrown one part at it.

That is a Wish & Hope-- Push & Poke Diagnostic Theory,
that only takes your money & you replace every part,none
of them being tested or bad

2001 kia sportage will brake lit switch cau the truck stall whil driving

Yes, If your idle RPM is too low it can kill the engine due to the high current of the brake lights will cause a stall.

Most cars use an RPM idle of 750 to 775 RPM. Check your manual then increase your idle a little.
Hope this helps.

When going up hills is the engine bucking and missing? Also for the hard start warm problem, check the fuel pressure regulator for leaks into the vac line.

Car is jerking in 1st, 2nd and 3rd gears

Our '06 sportage was doing this after some snowy weather last winter. My wife was briefly stuck in some snow and had revved the engine/spun the tires a bit to get out (ESP was going crazy for a bit). Have your local dealer reboot the computer. This solved our problem.

The radiator thermostat may be stuck. I've had that before. Just about any auto part store should have an employee that can help if you need it. Its a quick and easy fix/replacement. You'll definitely want to check your radiator coolant level as well.
