so i had a smoking problem where it was dumping blue smoke at idle and smelled like raw diesel coming out of my tail pipe had my injectors checked and was told #6 and 8 were not reading and they were not working so i needed to replace them... got 2 out of a running engine a replaced them and i still have the same problems/symptoms... could i have a wiring problem? couldn't possibly be anything else... could it??? oh! i almost forgot if i unplug #6 injector completely it stops smoking is there any easy ways to check to see if the wiring is shot?? do i have to replace my whole engine main harness?? what is going on? can anyone help please!!
