1993 VG30DE (J30t) Bad Injector

[GerryO]

A bad run all the way, to and from work today.

With the engine idling roughly and the Check Engine light ON, I disconnected and re-connected the wires to each coil pack this evening, one at a time, detecting NO change in idle speed at the cylinder #5 location.

I swapped cylinder #3 and #5 coil packs and the problem stayed with the #5 cylinder.

Measured the cylinder #1, #3 and #5 injector coil resistances at about 11.5, 11.8 Ohms and infinite resistance, respectively.

Since I replaced all of the belts, water pump, etc a few thousand miles ago, I'm considering replacing all six injectors, the PCV valves and the EGR valve?

Is there anything else that I should do at the same time and which is the best new injector to go with?

Could a short have taken out the injector coil?

I was in the similar position:

what i did was1) replace all gaskets. valve cover gaskets tend to leak2) replace EGR, PVC and O2 sensors3) You may want to replace the VTC solenoid4) replace all fuel hoses5) replace all water hoses6) replace fuel rail + fuel temp sensor

I guess the list can grow much longer. It all depends on how much you want to invest on ur J. I DID invested a lot and no regret! My J really is a graceful lady and a wild *****.
