Yeah here ya this one was the very last rocker on the passenger side, and then there is one on the drivers side, but it not as bad as this one all other rocker look fine.

 

Bump for anyone that was following this:

Finally got some new o2 sensors put them in same problem although it was a little better LT BLM cell 16 were 116-117 as to what it was before 108...So I then decided in a desperate last measure to try unplugging the MAF again even though it read fine in the logs, behold my blms jumped right up to 130:mad, but now they seem to be a little on the lean side 135-140. Could be it needs time to re-learn as I reset the BLMs still after alot of driving they held the same, or could it be because it now doesn't have a MAF?

Alot of pain and madness over a stupid issue like the MAF` I guess ill have to get a new one...

 

I have exactly the same problem with '95 M6 Formula. Car runs well cold and in open loop. As soon as it gets into closed loop, idle gets a little rough and at low RPMs as in take off it surges. If I let it coast without touching clutch, car will start jumping like mad. At idle I get between 109 and 111 long term BLMs in closed loop. I tried everything except optispark. Replaced both o2 sensors. Fuel pressure 37psi with vacuum on/43 with vacuum off. Installed another fuel rail complete with injectors from another car running lean at idle, installed MAF that was reading 142/144 at idle in another car and went stright down to 109 on this car. Disconnected EGR, reflashed and installed another PCM with no changes. When disconnected vacuum from fuel pressure regulator, BLMs bottomed at 108 on both side. Any suggestions?
