Message I took ParticleZX's suggestions and began testing the fuel injectors instead of the power transistor module. And sure enough, I found a bad injector on the number 4 cylinder (left bank, middle cylinder). The resistance measurement is 80k ohms vs. 10-14 ohms for a functional injector. It appears from the FAQ 'Causes of injector failure' that injector failure is inevitable given the ethanol content in today's gas.

I priced out a set of OEM injectors from Nissan and they run over $200 each for the complete assembly including o-rings, insulators, etc (i.e. $1,200 for a complete set of six). Can anyone recommend a less expensive aftermarket injector that would be a direct replacement for the factory injectors currently installed in the car?
