Richard Childress Racing endured its share of difficulties in opening practice at Richmond International Raceway on Friday.

Paul Menard was the first to have trouble 45 minutes into the first NASCAR Sprint Cup practice when his throttle stuck and the right side of the car slammed the wall. The No. 27 team was forced to pull out the back-up car. Menard experienced problems with a sticky throttle in the secondary car as well, but the brake disabled the shut-off automatically.
