Question about 2000 Kia Sportage

5 Answers

2000 kia sportage ex, 4 cyl.

Our 2000 Kia Sportage runs rough when stopped or slow many times, other times it does not run rough at all, when idling at a stop sign etc.
Is their a sensor that controls gas to air ratio or should I try something else.
Kia Sportage 2000,EX, 4 cyl., 2 litre, 4 wheel drive.
I thank you for your help.

    This Relates to Circuit High Input for Mass or Volume Air Flow

    This Relates to Sensor Low Input in Manifold Absolute Pressure/BARO

    This Relates to Misfire Detected - Random

    This Relates to Misfire Detected - Cylinder 2

    This Relates to Misfire Detected - Cylinder 3

    This Relates to Misfire Detected - Cylinder 4

    This Relates to Air Conditioning Compressor Clutch Circuit Fault

    This Relates to Bank 1, Sensor 2 - Circuit High Voltage for O2

    I have a 2000 Kia Sportage. My car runs rough at stop sign, runs rough on acceleration unless you almost idle up or barely give any gas.

    I have changed the fuel filter, fuel pump, air cleaner and had it tuned-up.

    The problem has come and gone for over a year and I have had it into several shop, kia and private. No one has figured it out. One guy mentioned it could be the TPS, so he traded it out with another used car he had. The problem seemed to go away for a while but now its back. I wonder if it would solve the problem if I replaced it with a new TPS.

Yes there is a sensor that controls Fuel/air ratio.It's called a MAF (mass air flow sensor)
But I think you should have the EGR (Exhaust gas recirculation)valve checked
and The TPS (throttle position sensor)maybe dirty.

Although may things can cause this issue,I would look at the items above first.

Please rate this a blue fixya

Many of the Kia sportages have a problem with the coils.

There are 2 coils for each 2 cyl and they are located under the middle platic cap on the valve cover.

These coils will set a check engine light that blinks when misfiring and stays on steady when the motor is running smooth. Autozone or Advance auto have a scanner that can check all engine functions and will show a problem with # 2 and 4 cyl.

The coil packs are $39.00 to replace but check the codes first

For that many codes I would refer you to a bulletin covering the 123 and 124 connectors. This bulletin has instructions on how to upgrade these 2 connectors which connect the engine to the ECM. The connectors are located under the intake manifold towards the firewall. You need to remove the battery, pull the connectors apart, give the male side a slight twist, then you add Stabulent 22 to the connectors and reconnect. The dealerships also add some clips to hold the connectors together better. This task is not an easy one due to the location of the connector. I have done it many times in the past and this helped many of my costomers. Anither thing to check is the continuity to ground at the MAF. This also can indicate bad connection throughout the engine harness. to upgrade this connection, clean the ground connections at the battery and under the battery tray. these simple uperations should have been made into normal maintenance for the 95 - 99 Sportages.

The sportages of the 1995- 2001 year group have a reputation for bad grounding. I took the easy way out and added ground wires from the neg. battery terminal to the body and the engine block, before I did this I had sensors throwing all kinds of codes, after only an occasional Mass Airflow Sensor code. but wiggleing the plug on the MAF to clean the contacts a bit sets everything right again. Just a little info to enlighten those who wish to know. Take it or leave it as they say.

My problem was the same as the first post, stumbling at idle and low speed. When taching up the engine to about 3,000 RPM at idle, I triggered the error codes P0300, 301,302, and P0304. If your MAF is giving a faulty reading, then you will having misfiring on all cylinders due to impropper fuel air mixture. I've had the MAF code for a while on my sportage and tried cleaning the MAF and the connectors and it still gave me the same error code. When I clear it it stays off for a while, but eventually comes back on. I would recommend changing the MAF and seeing if that fixes the problem. Its a very easy part to replace, but not cheap.

Symptoms 2000 kia sportage Symptoms 2000 kia sportage does not do all the time. Starts runs well but driving road 50mph almost as if ignition shut off split 2nd. Stop car and while running in drive s

Some makers used Vacuum releases for their emergency brakes which had a Vacuum switch connected to the shift assembly. This would account for a stumble if Vacuum vented out through this switch.

More common for shifting stumble to occur from Park to Drive, engaging a load on the engine, not to stumble to a freewheeling Park position. Sounds like idle speed control is sluggish to stabilize the motor.

You also have idle speed control problem with A/C, kind of shows that A/C was what kept the engine running because when you turned the A/C off, the car died.

I am going to give you some Websites for wiring diagrams. amd with free wiring info upon registering your vehicle.

It seems that the base Idle speed control is not working and the A/C idle speed control is.

Also check for Vacuum leaks on the intake manifold by spraying water from a pumpbottle on the seams of the gaskets.

Check ignition Relay or ignition switch for random cutouts. The fusebox layout is on the Autozone site.

I hope my solution helps.

HOLD keeps coming on in my 99 kia sportage what does that mean

Look on the shifter lever,just bellow the push button. There is another push button there. That's the one you press or depress to keep the transmission on 3rd. gear. Just press it again and the hold light should come off.
