my 2012 keeps popping a p0305 code. cyl 5 misfire. i reset it and it is fine for a few weeks then comes back. it has done it three times. what could be causing this and is there any thing to be concerned over?

 

head replacement maybe mine has tick but no code not loud though so they wont replace head

 

My jk goes in for surgery on Monday a.m. Said it'll take 9 hrs I figure ill get it back on Wednesday. Hope someone in quality control checked out this replacement head

 

im srill waiting but in a way hoping it dosent code. I realy don't want engine repair its not factory tight but, there again factory cant get it right so maybe the tech can do better than the factory, good luck and keep us posted in the difference in tick if that's what it was doing?
