Can o2 sensor or other sensor cause the engine to misfire ?

Thanks for the reply. I've 2 ignition modules behind the engine. Sadly I'm living in the middle of nowhere and I can't find someone to do a diagnostic on my engine. I was thinking about replacing those 2 ignition modules. Yestersay I've checked all the plug wires and they all look fine. I will check all ground cable today. I'll let you know if I can find the problem

The battery is new as well. It only backfired once. Otherwise Rpm goes down suddenly and i feel like push or shock like misfire and no power even with My foot all the way down hard to pass 1200 rpm sometimes Witch earth connection should I look at ?

Hello everybody. I'm driving a discovery 2 V8 ans I have a lot of problems. Now when I'm driving around 1500/2000 rpm,suddenly the engine rpm drop to 1000 and then come back to normal. Or I feel like a "push" or shocks when I'm driving Also it has less power and one time i heard a bang i think it was coming from the exhaust. I've put new spark plugs but I still have those problems. I don't know if I have to look at the ignition or the injector. Please if someone can help me Tks everybody
