CEL Codes

[MBXB]

OK I got a CEL on and finally read the codes:

0c, 0d - O2 sensors (theyve been on 100Kmiles)
19 Ignition Coil 1 (oil on coil due to valve cover gaskets?)
17 Ignnition Coil 6 (oil on coil due to valve cover gaskets?)
10 Cranks Sensor bad connection; ground?

Which do I attack first?

Thanks

check the oil situation in the plug holes and clean first, reboot the computer and wait for new codes.

Seriously the V8's will throw all kinds of codes for any one or multiple reasons. My take at cleaning the oil out (including inside the plug ends) is that is that shorting can cause a myriad of faults to be displayed. Once you know that is not the problem the resetting of the computer will tell you the next avenue of attack. I would venture intake leaks but I think I remember you posting that has been done already. If there is oil pooled the valve cover gaskets need to be done.
