FridgeFreezer Posted January 16, 2009 Share Posted January 16, 2009 Can I ask how you tested low-box? If you've driven it about on a hard surface with the difflock in you may not have done it any favours. Quote Link to comment Share on other sites More sharing options...
forkrentfitter Posted January 16, 2009 Share Posted January 16, 2009 coughing could be fuel sedimenter blocked,lift pump failing,air filter blocked,intercooler hoses collapsing,start at the sedimenter and check the fuel system. Quote Link to comment Share on other sites More sharing options...
