Like the old saying buy once cry once. Been here done that. Mine popped the p0087 code. After looking at fuel pressure figured out it was injectors. Bought brand new Bosch stock injectors. Best thing I did.
Changed front shocks on 2001 freightliner classic, replaced oil cooler fan on concrete truck, changed oil in a 2018 579 Pete, replaced tarp on concrete mixer and lastly blew a load of cement in the silo
My bosses 2019 just had this issue. Running great then boom hard miss. Shop trouble shot and said bad injector. Truck has 120k on it. I said I don’t think so sounds electrical. Replaced number 5 injector plug all good.
