My 2002 Yukon 5.3 idles right around 500 rpm when warm and the A/C on. If you turn the steering wheel slightly the rpm's will drop and it will sound like it wants to die for a second or two. I've cleaned the throttle body, MAF sensor, air filter, and removed the IAC valve and cleaned it. While it was out the tip of the IAC valve popped off and I re-attached it but am now wondering if that's what is still causing the low idle by being a step of two off. I had it at the dealership this morning and they updated the computer.
