[QUOTE="NessiFord, post: 451778, member: 24132"] This whole feed has been very informative, I have everything off my 2013 Jeep Wrangler JKU 3.6 (166k miles) engine right now…I did have a misfire in 5, but it went away after I got rid of the shell fuel my husband put into it…but I went ahead and changed out the injectors, because I was changing out the oil cooler filter housing and oil pressure& temp sensors, I have did spark plugs and coils not long ago, but gunna change out the plugs again since I’m here…I’m changing out the rockers and lifters also, got a tick after the oil cooler started leaking, I’ve done the PCV, super flushed it (my heat was working to well, it’s good now) but it’s been going in and out of limp mode, and getting the dreaded P0731… , I’ve already changed the TSS, fluid, and filter, gaskets, pin plug, and no difference…i changed the Crank before but now reading I need to relearn it…I have a scan tool so I can do that, but was just doing my research and came across this feed, and wanted to say thank you! I think I know exactly what I need to do now…and im pretty sure im going to go ahead and do all the O2’s as well…I know it’s been a while but if you see this, thank you for this post, this has helped me make sense of things…and I really hope you got that light off! I truly feel your frustration! Thanks again! -Nessi Tennessee [/QUOTE]
