Unhappy Idle Issues

Hello guy's,

I have a 2005 Kia sportage lx with a 2.7L V6 engine, I'm having some idling issue's with my sportage and would like to see if you guy's could give me some input on what the problem could be, My sportage idles at 4000 rpms when driving and cruising and when coming to a complete stop it idles really low and seems like it wants to cut off. So far i have replaced 2 oxygen sensors, Throttle sensor and the idle control actuator and it still idles really weird....I'm fresh out of ideas and solutions, Any thought's or idea's what the problem could really be.....Thanks's

It wouldn't be "idling" while you were cruising, would it? It should be doing about 2500 RPM on the highway in top gear. Assuming it's an auto, maybe it's performing so badly that you're in 3rd or 4th gear instead of top gear?

Catalytic converter can get blocked and cause poor performance.

Hello wry'Cuda Thanks for responding...It idles high when driving at a normal speed in 1st gear but it should shift like you mention at 2500 rpm's, its a automatic transmission. When i take off from a complete stop my rpm's go up to 4000 rpm's before it shifts to 2nd gear, When stopping at a stop light the idles jumps down really low like it wants to cut off. I always warm up my sportage to normal temperatures before i drive it...I'll see whats up with the cat converter...Thanks for the advice.

4000 RPM before shifting to 2nd gear is normal; if you keep going, does it get to top gear?

Idling generally means engine turning over slowly with the car stopped and transmission in neutral (about 700 RPM). There might be a misunderstanding in terms here.

When you come to a halt, the transmission should be "idling" in 1st gear and there might be a slight drop in RPM compared to neutral, but not enough to nearly stall the engine.

Not sure of your location and local temperature, but it is not usually worthwhile to warm the engine for more than 30 seconds. Unless there's a load on the engine, it will take a long time to warm to full operating temp.

a high idle like that can also mean an air leak, whee the engine is sucking in extra after the MAF (mass airflow meter).

Most idle issues result from some sort of vacuum leak.
