have you checked to see if you have a bad came or lifter. that would make it backfire. if it kind of spits fuel it maybe cam. if it throws fire than it could be timing like a bad chain.

Here is the procedure for setting the timing: Fig. Fig. 2: EST bypass connector
See Figure 2
When adjusting the timing, refer to the instructions on the emission control sticker inside the engine compartment. If the instructions on the label disagree with the procedure listed below, follow the instructions on the label.
WARNING Never pierce a secondary ignition wire in order to connect a timing light. A pierced wire may lead to engine misfiring and driveability problems.
An ECM code will be set when the EST bypass connector is disconnected.
To prevent ECM damage, the key must be in the OFF position when disconnecting or reconnecting battery cables.
