It is very possible that it is a coil going bad or the cam position sensor...

The tuner said it could very well be the fuel system cleaner messing with the tune and that I should get this tank out abd fill it with fresh e85 before I start replacing anything to see if that fixes it

Yeah that stuff you put in the tank does more harm then it's worth, never use it again.

Not known if that is what's causing your problem but that crap can assist the gunk build up.

Do not want to jack your thread, but I'm having the same problem. Have you figured anything out yet? I only have the problem on the freeway and mine throws a code. Egr insufficient, over-boost and random/multiple misfire. Please post if you've fixed your issue.

EGR insufficient means theres a vac hose that came off on the EGR stuff.

Misfires are most likely due to spark plugs, so check them/change them.
