My 02 Dmax 52K miles went into the dealer today for possible injector problems. They phoned this PM to say they were replacing 1 injector and denied any knowledge of having to replace all 8 when any had failed. I think this only applied to the the 01's & 02's. I'm sure that I saw a referernce to a TSB on this site that verified this. I tried using "search" but couldn't find anything. Any help would be appreciated because I'm going to see the dealer tomorro AM. Thanks.
