Could be a short in the wiring for the O2 sensor.   I currently have the same issue only my car finally threw a code after two days of it acting up.  Code 106.  Changed the MAP sensor and it now throws 108, MAP sensor high voltage circuit.  Ah the joys of cold weather and broke down vehicles.  But I know that you wont always get a code with a short.  Let me know if you fixed the problem.

SOURCE: idles high

Zab, First things first, check for any vacuum leaks, hoses that are disconnected, cracked or just plain worn out. Also check for vacuum leaks around the throttle body.
It really sounds like you have an EGR valve that is stuck open ever so slightly. The MAP sensor is a result of a low manifold vacuum. The IAC (idle air control) motor is trying to compesate and keep the engine running resulting in the high idle speed. I would remove the EGR valve and clean it gently with a brush and pick to remove any carbon build up.
Let me know, regards.

Have you checked for vaccume leaks?
You've got lots of parts in there, Has the problem been the reason you have replaced all of those, or did it come up while doing some of the repairs?

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.

I am not familiar with this engine. But, if the alternator, PAS and AC are being driven by the same belt, then its possible that the belt is too slack, have you checked the belt tension ? That would be my first step. Hope that helps

I have a 2002 Kia Sportage - idle slow when stopping at lights


Even though the fuel filter and pump are easy to replace, I would start with the IAC sensor first. It is easier to get to and is cheaper than the other two if you can find one at a wrecking yard (should be around $20). This sensor is the Idle Air Control sensor, and the computer decides how much throttle to give at idle from the readings of the sensor. If it is bad your car will idle poorly or not at all.

You can verify this two simple ways:

1. Disconnect the sensor completely and see if anything changes. If you get the same issue, then it's probably the sensor. If different then it could be fuel delivery.

2. With it all hooked up; try throttling the engine yourself at 1000-1200 rpm and see if it is smooth. If it is then it is probably the sensor. If not then could be the fuel delivery.

The sensor is under the silver and black, plastic KIA cover over the engine (4 small nuts to remove), and is center above the engine on the front side of the intake pipe.

The part looks like this:

If it seems to still be fuel delivery, the filter is (facing the engine from the front of the car) down to the left and toward the back attached to the fender well (Just to the right of and below the battery)
