I have an issue with Dodge Durango's 4.7 Liter V8 engine. It is "rocking" rhythm gently for long time while idling but accelerate smooth. When transmission was placed to Park or Neutral, Engine runs smooth.. Sometime I just lightly press accelerator just to move truck 1 or 2 mph during traffic and it makes my head bobs a little ( ). It's getting in my nerves right now.. It seem one cylinder is misfiring or something. It already had new sparkplugs but problem remains the same. Coil On Plug (COP) are plugged in correctly and there is no corrosion on wires or cracks on its shell. One of COP had reddish powder on its tip. I cleaned it and put it back in after installed new sparkplug. I did not put COP in order while replacing sparkplugs, I just plug it back in whichever is first pick because it works the same regardless. I wanted it to run smoothly. Sometime engine ran smoothly and other time it rocks (moody engine) depending on weather condition. There is no antifreeze (white smoke) or oil burning (black smoke) ect. I smelled exhaust and it's all normal.

Currently, I have engine light lit on since last summer (I replaced oxygen sensors). It turns off but later when weather became cold, it went back on and never bother to shut em up yet, just being lazy not trying to fix it. Does defective engine sensors causing engine to rock?
Question is that are V8 engine's gentle rocking motion normal or should it be smooth regardless?
