Hey guys just made an account to get some help with this issue, so I had a low rough idle problem at cold starts and decided to clean my FITV, i dissembled it and then reassembled it and found lots of rust into the flow port for the valve, after it was cleaned i put it all back together and did NOT touch the iacv, now my car idles at 4,000 rpm also noticed my throttle gasket is in half but i bolted it on tightly i dont know why its so high pls help ;-;
