Drove 15min to lunch today, no issues. On the way back, engine dies. Restarted and kept driving 4 times until it finally wouldn't run. Didn't want to call a tow truck so I disconnected the #5 injector electrical connector because the codes confirmed a short circuit. It ran rough but I drove it home.
Resistance across the injector pins should be apparently between 170K and 210K ohms. While mine measured 210Kohms, the resistance between one pin and ground was 5K. The other injectors measured higher than my meter could read.
Took off the intake and tried to remove injector #5. Of course it is seized. Soaked it down with a penetrating lube. Hopefully I can remove it in a couple days.
While I'm in there, the intake manifold (including flaps) will be cleaned. There is about 1mm of CBU. Not too shabby for an M57 at 90K miles.
