[QUOTE=78F350;600925]I think the info in this post on Renntech is more accurate:
https://www.renntech.org/topic/32802-error-codes-p1128-and-p1130/
Lean condition detected by the primary O2 sensors that cannot be corrected by the DME.
Think: Too much air, or not enough fuel, or sensors on either end (MAF or O2) are reading incorrectly.
and here's a pic that was posted on Rennlist:
...not that I'm particularly smart on this, but I've been dealing with it intermittently over the last month on one of my cars.[/QU
I just looked up the codes in the Bentley manual and relayed them in my post. With the Bentley saying "short to battery positive" I would still check the things I listed in my post to the OP. If all was ok I would then look to the to much air not enough fuel scenario. As the Bentley states the system is calling for enrichment beyond the upper limits of the system. Vacuum test for excess air in the intake. exhaust leaks ahead of the O2 sensors. If all ok then on to fuel issues.
