PONTIAC GRAND PRIX PROBLEM

2004 Pontiac Grand Prix • 140,796 miles

Tach started to fluctuate, then car lost power, tried to accelerate several times and would not go, then all of a sudden car went full throttle. Tried hitting the throttle several times, then it just started to run fine. Checked for codes and there were none. This a drive by wire system. Any help would be greatly appreciated. Thanks in advance.
