Cleaning the ISCV made no difference, I also switched for one I knew to be working fine, again no difference. I intended to have a another look yesterday as I had the day off but I had to change my front springs as one snapped and the top mount bearing were fooked so did them and the arb drop links. Anyways, the top of my n/s strut was fooked making it impossible to get it undone, so had to replace, and then the bottom of the strut just didn't want to go back into the hub, so ended up taking all fooking day and I didn't get chance to have another look at my idle problem .
