Strange idle I had my car dyno tuned a couple months ago, but I have a weird idle problem. It will idle normally at ~800-900 for a little bit, and then all of a sudden it will jump up to 1500 and idle there for about 10-20 seconds. Then it will drop back down. Also, after making a pass under WOT, the idle won't drop back down below 1500-2000 until I stop the car. I have to stay on the brakes because it wants to speed up. I put a new IAC sensor in hoping that might fix it. It's a 427 with a TH400. Thanks.
