fjh Posted February 4, 2011 Share Posted February 4, 2011 The light comes on every now and then, is the injector sensor serviceable? is the injector 3 maybe clogged? Thank you for any replyRon You have a unit pump that is starting to get glitchy just run it till it starts getting trouble some,this can go on for months / years If it becomes to frequent then do somthing with it!Yes its servicable but you need to have the Cal code installed at the dealer ,Also note! If I were you I would take the covers off the unit pumps and check all the bolts for tighness, I did one yesterday (Pump three ) the bolt on one side was about to break ,when I went to remove the pump the bolt broke off and the other was loose This May be the cause of or just a symptom of your problem.
