Check the 8th digit in the VIN; 1=LB7 and 2=LLY. LB7 number issue is injectors. Look forward to getting 70K or so out of each set. That seems to be what most of the around here get. They are warranted for 7 or 10yr/200K, IIRC. Other than the usual injector harness rubbing, tie-rod issues and likely pump rub they are not known to have a lot of problems.
