On the way back home on a 900 mile trip in the mountains, the B2's 2.9 started cutting out on some cylinders. Once home I checked compression -> 150 on all. Ignition seemed okay, although the spark was yellow. I suspected injectors all along so I pulled them all........ 3 of the injectors were stuffed with rust grit. Odd thing is, the injector next to it less than an inch away had NONE! How would that happen? I'd guess the only sources of rust would be the fuel rail, and the tank.......

Last time you replaced a fuel filter?

Also. The insides of the fuel rails will rust. The one on my 1990 parts truck did, at least.
