sound like really bad throttle hang/rise. My 99 SVT did that really bad for a while. I just reset the computer and that took care of it. Try that first and If that doesn't work, try the throttle hang fix. More than likely one of those two will take care of it. -neal
99 SVT...modified 96 GL....the beater "I live my life a quarter mile at a time. For those 14 to 15 seconds, 16 if I get tire spin, or get a bad jump, or possibly if I have a friend in the car, I'm free."
