Thanks - I did take it apart and drain the fluid, sprayed it out with the appropriate spray and nylon brushes, reassembled it and put it back together. The screws were a pain and I did strip 2 of them but got them out and replaced. the gasket seemed fine so I reused it also. I was just wondering when I replace it, if I need to recalibrate anything. Also, should I replace the IACV and throttle body or just IACV?
Thanks.
