Misfire cause timing dip without knock count?
My lc-1 failed twice and ran like crap for a little bit so I pulled over and stuck the factory o2 back in. Now I've notice an intermittent hesitation while cruising. While logging I seen its pulling 14* timing about every 4 seconds with a dip. Is this a pcm response to the misfire/drag?
I even swapped back to my old map with Maf and still does the same thing.
Plugs in it now are the old acdelco 41-985. Swapping to tr6 tomorrow.
