Hmm. By now I've been filling the car up from Caltex DHA KHI religiously and that too from the same fuel station I used for my reborn for a long long time however I shall try and change the fuel to high octane and/or change the station to see if it helps.
No worries. I shall update this forum on what helped and what didn't etc. That's what we're here for
