Allways reset the computer by disconnecting the battery for at least 1/2 an hour if you run the engine with a sensor disconnected. Another thing you can test is the knock sensor. To check it is working you need a timing light and another person. While the engine is running watch the timing as the other person taps on the block right next to the knock sensor do not tap on the sensor itself they are real brittle. The timing should retard with the tapping quick taps with a large wrench. The knock sensor is on the block in front of the starter clean the connector good it usually gets real dirty from its location.

Alright after a couple days of tweaking, breaking, smashing, and crying, I figured out why it is backfiring. My accelerator pump had lost it's flexibility and wasn't supplying enough fuel. I replaced the accelerator pump and the backfiring went away. Runs and drives great now.
