At the last GoodGuys show the wife was driving the Dart and I was driving the Challenger. When we were leaving she bunny hopped a speed bump (more like a mountain) anyway tore up the header bad enough that it wasn't sealing at the head. (Check my thread for Pics) Just spent all of this last weekend getting it back together with new headers, and a new plug set. She's all better now (the car) but is idling fast now. I think it is a vacuum leak as I took the carbs off and cleaned them and just ran out of time to dick with it......... it will be my project for next weekend.
