Probably ignition-related.

Change spark plugs. Use standard NGK copper plugs (yes, the cheapest ones), gap them to 0.8mm and replace every 20,000km or every year, whichever comes first.

Change ignition leads.

Ask a mechanic to check your ignition coil(s) and oxygen sensor(s). Replace as necessary.

You will also want to check your intake pipe & ducting for damage after backfires.

If you have done all of the above and problems still persist, contact your local gas installer for a gas system service & tune.
