i've got a 79 Lincoln Continental Mark V and it has a stumble right before wide open throttle. if you slowly rev it it goes up fine. Floor it and it backfires right before WOT. What could be causing this? there is no slop in the accelerator linkage (2bbl. ) Im stumped. thanks guys.

Lean air/fuel mixture. Check for vacuum leaks and as the previous poster said, accelerator pump would be a good staring spot.
