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.

Righto,here is a log of this engine.Was really just a drive up the road.Not a lot of power and popped a bit under acelleration so didnt try to push it.Would be keen to see what anybody thinks

Turn the knock control stuff off its continuously pulling all your timing out you were driving along at 2.5 degrees of timing.it has a tps low volt error get it idling with some timing and get some vacuum happening so the tps error doesn't trigger

knock retard strikes again. I always turn that crap off, never seems to work on the best of days.

Can't beat knock ears for the real thing.

Thanks for the help.What is the best way to disable the knock.The table shows three items about knock.The parameter finder brings up a lot more. Where am i best to look please,

I thing it was called ESC enable temp or something like that. And set it to the max of 150.xx C so it can never activate.


EDIT.

yep ESC param- coolant temp enable

correct Vlad

Found it.Many thanks
