Early 01 LB7, built 11/20/00 with 55K went into limp mode at 54K ...all new injectors. 1000 miles later throws P0089 FPR. Dealer can't repeat problem after 1 week of starting each day. Has always had "loopey idle", ie slight but constant flucuations in RPM. Question is whether new code on FPR is a result of problem with new injector install. Dealer scan check shows fuel pressure within spec range. Left dealer and within 100 miles SES light came on upon restart and later went out. New fuel filter installed after injectors replaced.
