Narrative:

When the power levers were brought up only the left engine spooled up. The runway condition was less than good. The aircraft began a right swerve. The power levers were brought all the way back and hard breaking applied. Only when left reverse was applied was the aircraft stopped. Total swerve was close to 90 degrees. The aircraft remained on the runway and we taxied off the runway and returned to the gate. The flight was canceled. Maintenance and dispatch were notified for maintenance action.
