Maybe redo the plugs as well Link to comment Share on other sites More sharing options...

Found out the passengers side half shaft is flogged and after joe checking the tune it still has the slightest missfire at high vacuum/light load and it idles strange still and the fuel economy is still 3l/100km more than the trip meter. Gonna replace the plugs and maybe find a .8 gapped plug. Fresh ZF feels wonderful though. Link to comment Share on other sites More sharing options...

The only thing left is injectors so I'm considering ordering some KPM ones and see if that fixes it. This issue is driving me up the wall. And I still have to do the CVs but that's another job on the list Link to comment Share on other sites More sharing options...

Yeah....no. That's not how that works. Were all those other parts "try and see" items? Save your money and take it to someone who knows how to properly diagnose it.
