Chasing P0301 - How does my idle sound?
Hey folks,
I've had an issue with a P0301 code, and I was wondering if my idle sounds normal for a 4.0L. Please take a listen and let me know.
Is that a misfire?
Also, should my fuel pump be that loud?

Get a can of starter fluid or use a spray bottle filled with plain water and squirt (on stream rather than spray) around injectors. If the sound smooths out then replace injector o-ring. Next, check 02 sensors.
The dirty rag kinda says 02 sensor but checking injector rings is quick and easy.
