Here is where it started. I was going to trade it in on another vehicle when the dealership test-drove my sportage they came back and said at one point the car did not accelerate past 25 mph. So I took it to the mechanic who plugged diagnostics tool and told us it may be the camshaft or crankshaft position sensor. Well neither part was handy available. So when I got home I did some troubleshooting myself. 1st. the vehicle hesitates at times, 2nd. idle sounds like it is going to die, 3rd. sometimes there is no immedite response to gas pedal. I unplugged IAC sensor and cleaned it up. While doing that I noticed that the car ran better when the ICA (idle control sensor) was unplugged, although exhibited same symptoms. Any ideas.
