Injectors?

 

[IdahoRob]

I did. Had them do the lastest reflash. That fixed the problem. They didn't think it would work, but I asked them to "humor me". Problem solved.

bad injector

Bad injector! Mine did the exact same thing and dealer replaced #8. Fixed it.......Numerous prior comments about the same thing here.
Good Luck!

I would have Injector wiring harness checked, then check #2 and #7 injectors. Have been known to go bad first because the wiring harness is bad.
