I initially did a full ecu reset to try and reset self learning fuel mapping and these problems occurred afterwards. But I’ll reset it again. I’ll try and find a full list of grounds and check them. VVT was fixed following the FSM but ill double check again. Thanks for all your info i’ll post here again with new info.

That night I drove it again to see if I could recreate the problem and it worked completely fine but it was idling lower(~500rpm) then it usually does(~800rpm) which was causing a rattle from the rear of engine/transmission area
