Hi all, have been searching for a few days, and can't find the exact cause to my issue. My r33 gtst wont slow down when I deacclerate without the pushing the brake pedal. Mostly noticeable in a car park when doing 10kms it keeps a constant speed without my foot on the accelerator. When I push the clutch in to park it idles around 1500 for 3 seconds and drops to normal. I have cleaned my iac valve, and going to clean my afm tomorrow. Has anyone had this issue before? Any help would be greatly appreciated.
