Not true for me. But I know what you mean.
My oldest 95 Maxima was running rough a few weeks ago, then the check engine light came on a few days after that. I checked the error code and it said "Cylinder 2 misfire".
I checked and verified that the coil pack was doing its jobs. I replaced that sparkplug ($3.00) although it still looked good. Resetted the computer. The problem did not go away, the engine was still rough, and the same error code came back a few days later.
I checked the injector, and sure enough it was bad. The resistance was 100 ohms, way too high compared to the neighboring injectors (12 ohms). Bought a whole set of 6 used injectors at a junk yard for $55. Replaced the injector and voila. Total cost $58, and I still have 5 good spare injectors on hand.
