Couple weeks ago, there was a pop/bang under neath my hood. My dodge started vibrating. She still was drivable. (But seriously I thought a cat got underneath my hood.) my brother change out my cool paks, spark plugs, and wires. He thinks my motors mounts are bad, someone said my o2 sensor, I was thinking my fuel injector, someone said my flow mass intake.. it vibrates when idling or coming to a halt when I take off its sounds like there is air in there. Or when I put it in park and ram up my engine and when it wines down it sounds like it’s going to die. But it doesn’t. Anyone else have had these problems.. or just change the parts out one by ones

if it's the 3.7l engine most likly cause ( because of the bang ) would be a rocker arm has popped off, has happened to a few Nitro owners here on the forum, you can check by simply removing the rocker covers,

don't drive it until you take the valve covers off and inspect.

Can do further damage.
