Hi, I am having identical issues as, listed on forum, on my 2015 journey 3.6 with 78,000 miles . rough idle at stop but no rpm fluctuations at any speeds. P0302 code only. Code will not show when cleared and then driving at speeds over 1200 RPM but shows up again at slow/idling speeds in parking lots.

 All plugs and #2 coil pack replaced, no change, code P0302 after 2 miles of city spped driving.

 Have owned since new,  filter and oil changed with 5W20 Castrol every 5000miles. Car does alot of short distance driving , less than 5 miles about 12 times per week with a few 16 mile highway trips in between.

 No coolant temp issues as per the coolant temp guage.

 I have NOT changed the PCV valve so maybe oil contamination in intake but that should affect all cylinders not just the #2.

 No mechanical noises obvious from engine. Scan tool shows all injectors are within range and similar to each other.

 Please help, cannot afford a new cylinder head.
