Misfiring in natural gas operation Engine code BSX

Hello everyone, the forum looks interesting!

I drive a 2012 Caddy 2K with the BSX Ecofuel engine. I've already replaced the ignition coil, spark plugs and ignition cables, but unfortunately I keep having misfires when running on natural gas under load with a hot engine, which causes the engine to switch to gasoline operation and the engine warning light to come on.

Can anyone here help me?

Hi. Any error codes? I'm betting on 1st lambda sensor in exhaust mannifold. I had the same problem in my bsx engine.
