If it still won't stay running something else must have gone awry I think. The last tune we put on the NVRAM was the same one that was running it previously, so it shouldn't be any worse.

I'm thinking start with balancing the throttle crack on each throttle body, make sure the IAC is working and hopefully get it to the point that it will run long enough to record a reasonable log. When I last saw it the vacuum was pretty poor too so maybe a leak check would help. We probably need to spend a little time and go back to basics with the engine now that all the computer stuff is working.

Okay good advice thank you. Did have manifolds off recently to fit wideband sensor so may have not sealed again properly.
