Hello. I'm getting error code 1247 from the stomp test on my M50 Vanos swap. That code is for the "Ignition Secondary Monitor". There isn't a lot of information on this online or in the Bentley, so I was wondering if someone on here might have some insight into what the problem might be. The only issue I've noticed so far is a slightly rough idle and the car is running really really rich (diagnosed via my wideband A/F gauge). I let the car idle for a while tonight and at one point the idle flattened out, and the A/F returned to normal, but then the idle changed again and the gauge went back up into the high 16's/low 17's again. Any help is greatly appreciated.

16/17 is lean.... -
Sorry, typed wrong. Yes, it is running lean. Could this be an issue with the ICV?sigpicLevel Motorsport: www.levelmotorsport.com

Since no one has weighed in yet, I figured I'd update. I went to the junk yard and pulled three Cam position sensors (I figured one would have to work). The first one I put in and reconnected the battery. CEL came on immediately so I did the stomp test again and the code changed to 1281 (Control Unit Memory Supply). The car is still running lean at 16.5. Any thoughts?sigpicLevel Motorsport: www.levelmotorsport.com
