Interesting piece of kit that OBDII

Yes, very helpful or leads one in the wrong direction ... it is easier to diagnose if I had full engineering specs to go by ...

I left the variocam unconnected and drove around the block and it ran fine up to 25mph ... so I am left to pull the bank1 head cover and take a look at the variocam ... checking for anything odd such as really worn pads. Might be able to get to it this week ... just need to make a hold down tool for the cams. I'll update my progess ... thanks again for all of the input.
