Any thoughts on the likely culprit for a constant engine miss when the gas pedal is to the floor? The stumble happens if you floor the gas pedal to access passing gear, as well as from dead stop. The car (318 poly - automatic) starts right up and has smooth acceleration at normal part-throttle gas pedal positions.
