Check the cap for cracks and look for signs of tracking.

If all you did was replace the plugs and wires, and it ran ok before, then you know something is wrong with the wire routing. A bad wire or plug will make it run rough, but i dont think it'll cause a back fire.
Check the wires again... firing order should be 13726548 counter clockwise. I'd remove the number 1 spark plug, and turn the engine over until number one piston is tdc on it's compression stroke, then take the cap off and make sure the rotor is pointed at number one, then check the firing order from there.

But once you're sure you're at tdc on the compression stroke, just pull the cap off and the rotor should be at, or close to the number one plug. If it is, then like i said check your firing order from there.

Well....the balancer is the circular thing down at the front bottom of the engine below the water pump. It's got a lot of marks on it, with a little timing pointer bolted to the block pointing to it.

Oh, I know what you mean.
Well I think I found the problem. Popped the cap off and the metal piece that spins around on the end of the rotor (dont know what its called) was busted clean off.
