what idle issues are you having mate? i some times get weird idle, what it does is i take the car out for a spin idles spot on about 1000 revs when come to a stop and put it in neutral then i stop the car and about 30 mins later i start the car again and my idle drops to 500-600 revs when put it in neutral gets its pretty annoying but i have ran out of ideas bought a new ICV, checked for air leaks etc
