I have 98 with 160000 on it and I brought it to the dealer because of bad shaking when I would go about 45 mph and rough idle and check engine light blinking. Dealer said my # 4 injector was bad and to replace it would be 700 and to do all6 would be 1200. I have other maint I need to do as well just wanted to see if anyone has had to replace there injectors and about how many miles they gotten on the original ones thanks
