03 maxima se Knockin sound from engine and gas smell

Knockin noise. Can anyone throw some input, just changed all 6 spark plugs and the coils. Car is knockin at idle and in drive when you hit gas, kind of sounds like a boat. Can also smell gas but no white smoke comin out from exhaust. No codes or check engine light

The engine is likely about to throw a rod bearing, catastrophic failure is imminent. Serious. Get ready to put a new motor in or move on.

Is that where there is slight jerk as well when I hit gas? Kind of like a bad tire rod feel
