I have a code p0087. Have replaced the svc , fuel filter. Checked the fuel pressure to pump and all good. Will run for a day then derate. They will pull over, shut down then restart and will seem to run fine. Could I have a bad fuel limiter? Is this common? I also have a #2 inject code. Could this be caused by the low fuel pressure? No one has been able to direct to resolve this problem without just changing parts.
