Thanks Bob - the reason I like this forum is because of the advice from the "old fat guys"

I'll definitely give that another go. I wonder if my Actron box is just a bad one.
My O2 sensor was definitely kaput though. No voltage at all.
Jason, I'm pretty sure my Actron read about the same as yours is behaving. I'll digg mine out and give it a go and see what I get.
Looking at your video it seems like air leaks to me. Check all the hoses (I had loose connections around the hoses connected to the throttle body ports), the big rubber CIS hat (mine had big holes in it). Spray some carb cleaner around the runner seals and in the injector intakes (mine are leaking). I also had a huge leak from the cork gasket on the oil lever sensor on the oil tank. It's a wonder it ran at all.
