HI. Ok, there are several areas of concern here. I will list them below. 1. Timing - There may be some timing issues that are causing this backfiring you are experiencing. It is recommended to check the timing chain or belt for looseness. The chain or belt may be worn. A bad timing chain or jumped timing sequence can induce backfiring, in most cases. have it inspected, asap. replace if needed. 2. Firing order - Make sure that the firing order is in the correct sequence. 3. PCV Valve - Make sure the valve and boot are not clogged with carbon. This will cause a back up in the emissions system, thus, inducing backfiring.. replace the boot and valve, if needed. 4. Ignition coils and module(if equipped) - Inspect all coils that are assigned to each plug for proper operational status. Make sure each coil, if equipped, is functioning, correctly. 5. Distributor cap and points - Make sure this device is functioning properly, if equipped. Check the points for oxidation and proper point dell ranges. 6. Spark Plug gaps - Inspect the plugs for a proper gap. reset if needed. 7. Exhaust valve - This will be the most expensive repair. There may be some issues with one or all of the exhaust valves. one may be sticking or several may be burned. this will cause back firing, in a severe case. The entire affected head should be rebuilt, in this case. Ok, you will find the culprit in one of the stated areas above. I suspect a failed timing chain or belt(depending on what type and year the engine was manufactured). The chain may have become loose, thus, inducing a jumped timing mark. This will damage the valves in the head. mainly the exhaust valves.
