this is a serious safety issue! I would have it scanned and check for codes, throttle position sensor failure is the first thing that comes to mind and although the manufacturer has designed triple redundancy into it's design, the real world is very different than the paper one and I have seen some wacky things with throttle bodies and tp sensors.
