Pontiac Sunbird running on two cylinders

  • PONTIAC SUNBIRD

I have a 94 Pontiac Sunbird. While on the interstate, the car all of a sudden lost a great deal of power. Barley made it home. With the car running I pulled off one plug wire at a time. 3 & 4 cylinders - no change in performance. 1 & 2 the car would die.
I got an orange spark to jump from 3 & 4 wires to the engine from an inch or so. Could'nt compare to the others because it would die.
Any ideas? Please help.

If the 2 cylinders that aren't firing are of the same coil pack, switch the coil packs to see if it changes. A good spark is blue.
