What engine and has it been modified? Check for cracked cap around coil/coil wire, coil for resistance and see if firing order is correct should be on manifold.

After checking what I said on previous reply then check for a broken/bent pushrod or something similar short out spark plugs one at a time to try to find cylinder that is giving problem. If it "spits" instead of backfire that is totally different that can be an ignition or fuel problem.
