ive owned my 300c for a few months now and havent had many issues with it, but recently if i step on the gas hard (going from 35 to 60 or passing) my car will accelerate for a few seconds before cutting the throttle off. if i take my foot off the throttle and put it back on it will come back. there are no lights coming on when this happens. my car has the 5.7 hemi. thank you.
