SOURCE: 1999 KIA Sportage idling too fast

You might want to go to your local AutoZ to have them hook it up to a code reader and give you any trouble codes that may exist, but chances are you problem is going to lie with one of three things. The first thing I would check is the Mass Airflow Sensor(MAS). The MAS sensor is usually connected to the plastic breather tube that runs to the air filter. The next thing I would check would be your Idle-Air Control Valve. Not too sure where Kia put their IACV's at, but AZ's website should have vehicle specific repair info through Alldata for your Kia. The last thing that I would check if you still haven't fixed the problem would be your EGR valve. Other than that, the only other thing that I can think of would be your throttle positioning sensor, but this possibility is least likely. Hope this helps guide you in the right direction. Have a great day!

SOURCE: unstable idle

Check to see that the air meter hose that goes to the throttle body is in good condition and not cracked or torn, If you are getting unmetered air it will cause the surge condition. If you have had a tuneup lately, part of that is taking the hose off to get to the filter...
Good luck...i hope this helps...

Remove Air filter and all related housings including right hand side next to battery. Sensor is underneath fitted horizontally into camshaft end housing and front facing. Electrical connection also faces front.. Remove electrical connector. Fixing bolt is underneath sensor. Warning - on removal some oil will escape.

Picanto air con

Hello Sir:

not sure that I have a solution yet but I do have a few follow-up questions.

1. Is the airflow diminished from what would normally be expected? If so, open the Glove Box and remove the rubber stops on either side. Lower the Glove box so that access to the air inlet filter is gained. Remove the plastic securing clip and remove the air filter. Clean or replace as necessary. Also, run the fan with the filter removed. Does the airflow get better? Has the sucking sound disappeared?
2. Start and run the engine at idle; select the air condition fan on "low." engage the AC switch and note engine idle rpm: it should first drop momentarily and then increase. If the RPM does not drop, suspect the level of Freon in the system as below operational pressure limits. Most air condition systems shut down when the refrigerant pressure drops too low.

happy to answer any further questions and apologies for the delay.

Kia picanto 1100 starts but doesnt want to rev up

Hi,there is a common fault on these cars,that is the cranksharft snaps just behind the crank timing gear,this causing the ignition timing to run at minus and thus the car gets spark after petrol has been injected.the car will run rich and also damage the plugs.the pick up sensor can also be faulty.this can all be checked by taking the bottom cover off and checking,except the sensor has to be checked with diagnostis scanner.most likely it is the broken crank.if u in the Durban area I can help you.

Although is could be a fuel filter, it could also be a fouled spark plug, or a bad spark plug wire. Once you've ruled these things out, the problem could be the TPS (throttle position sensor). This controls your idling speed under all conditions. A faulty TPS will usually idle fine when the engine is cold but once warm, will tend to sputter and in some cases, stall.

if your vehicle has electric fans they may not be working you need to check that they are working let the motor idle until it starts to overheat & see if the fans are working ,if not check for blown fuse,or loose wiring connections,it could also be the temperature sensor that activates the fans,it may be faulty......hope this helps.....sherrs

While car is running it idles up and down . all sensors and valves have been replaced even tps and pulled code and it still said tps is bad
