Replaced all 5 injector with an inexpensive set of generics so I can have 4 good used ones for backup. Code is gone and car running exceptionally well.

Pulled the injector wires and tested the injector and connectors / plugs. All connectors / plugs have voltage and number 4 injector shows open circuit while others settled at 12.2 ohms. As long as they are all close it's fine.

To test the voltage at the connector turn the key to second position and measure. Do not start the vehicle or else you will be measuring pulse rather than steady voltage. You should have about the same voltage on all 5 connectors. Looking down at the connector while attached, the right side should be positive but I don't believe it matters while checking as most DMM are self correcting. Again, as long as the voltages are about the same the circuit should be good.

UPDATE: After the coils there was remaining a lighting fast hesitation remaining at higher speeds that I thought was transmission shift or torque mount related. Turns out to be the worn and weak coil under the Charge Tube. Both the bad injector and coil were under the charge pipe. Probably the extra heat cause them to go out before the others. Still under 84K miles.

That is interesting, as when I removed the sparkplug cover on the 02 XC70, and removed the coils, the coil boot was petrified in the cylinder below it and split.

I think like you suggest that the charge pipe is heating that area to a much higher degree. I was actually thinking about this when I first found that and was thinking if a small metal heat shield could be made to deflect the heat away. Perhaps using modified spark plug cover bolts?

Wow, petrified and cracked. I know the necks on two coils of the 00 S70 NA crumbles but a petrified boot. However, a new set of coils at 100K or less is probably good maintenance so no need for the shield. May cover the area further trapping more heat.
