Nornally reson for backfire is when intake Valve open Internal combustion in Cylinder. Pls Check Your Ignition Timing & Valve Timing. ( I think Your Timing Advancer is Defect )

SOURCE: Jerking on normal acceleration.
You might try a TPS switch. It should set a code but yours did't. The throttle position sensor sets the spark advance and fuel flow to match. The other possibility is the EGR system which also should set a code.
If you have not changed the fuel filter,try that because if you accellerate hard the fuel slooshes to the back of the tank.
In normal driving the contaminents lay on the bottom of the tank.

If the two dead cylinders are close together,then the head gasket may have blown out in between them.See if the timing has jumped.If it has a coil pack,the the coil pack may not be firing the two dead cylinders.

Determine whether the jerking is engine or transmission related. One way to determine if it is the transmission lock up converter is acting erratically is to down shift out of OD. And see if jerking persist. If it goes away suspect transmission to have problems with torque converter or TCC solenoid . If it doesn't go away determine whether or not the engine sounds to be misfiring. If so vehicle may require a tune up. Many vehicles can be diagnosed for free at your local Auto Zone.
