DJH Posted September 26, 2013 Share Posted September 26, 2013 I have a 06 Mack MP7 that dies when going down the road and takes a lot of cranking to restart. Any idea what could be the problem?

boyd Posted October 4, 2013 Share Posted October 4, 2013 Injector cups, they have a update on these. It will need conical kits. Which will be stainless steel injector cups. The problem is when you go to the stainless cups you have to replace all injectors also.. And even going with the conical sets, I have had these cups fail also. Hope this helps.
