912iS issues w/ running rough and lane light

I did not clear the logs last time but I’d imagine these are date and time stamped. I’ll go ahead tonight and repull them and once again send out to get read. With regard to the cps sensor comment, leaf just said to check the wiring for chaffing or burning which The mechanic did and found nothing. If I load logs on these forums as well is anyone able to read them? 

For anyone that wanted a look at the log files I have attached them. These include the recent faults, and the previous faults on Cyl 3&4.

Went out an cleaned up all the spade connectors on the coil packs the other day w/ electrical contact cleaner and then put some dielectric grease on each before putting back together. I had also noticed w/ Bill Hertzels help a ignition wire that had a spot that wasn't entirely wrapped in sheathing and was resting against my intake manifold. 

I'm not sure which of these might have been the cause but I logged 3 hours last night without the Lane light coming on once. I visited 3 airports an did over 15 landings so I was constantly moving the throttle around (which seemed to trigger it pretty often) and nothing happened! Thanks everyone for your help and I'm hoping my problems are over.

Just wanted to leave some followup as to my results so anyone with the same issues could hopefully find a fix. I am so far 6 hours in after cleaning up the spade connections on the coil packs and have not had any issues w/ RPM drops during lane checks, with nominal current not reached messages in my logs, or with my lane lights going on. After spending $2,000 w/ my AP to fix this I was finally able to fix it on my own for a $10 can of electrical contact cleaner and a $8 tube of dielectric grease. I found a thread on here from a few years back that pushed me in this direction and I thank everyone for all your help as it appears to all be fixed!
