A faulty oil temp sensor in the sump can cause the engine to hunt, do you have diagnostics that can read live values? Andrew

No don’t have any diagnostic at the moment,I’ve had to take it off the road,when this happened,we got the codes read at my local garage and it showed just about every code that was possible.they gave up with it told me to scrap it

First thing i would do is get yourself an Autel Ap200 so that you can read the codes Andrew

And start by clearing all the codes then see which ones come back. .
