2G Intermittent Injector Firing Problem

[Artago]

Getting a P302 code. Injector 2 stops firing sometimes. At a red light it just stops. Sometimes, if I turn off the car and crank it back up, it will work until I hit a red light then stop firing again.

Troubleshooting:
1. Swapped 1/2 plugs, wires, injectors. No change.
2. Bench tested injector 2. Works.
3. Spark test on cylinder 2. Have spark.
4. Unplugged / replugged injector 2 plug. Sometimes, it kick on, other times it doesn't.
5. Tested all 4 injector pigtails. 44.7, 44.7, 42.7, 44.7 Ohms

What can I test to diagnose the problem?
What's the injector resistor pack?
Could that be the problem?
How do you test that?

I'm starting to suspect the CAS or ECU. Can ECMlink log those values or do I have to test it some other way?

I started a thread on it here: http://www.dsmtuners.com/threads/2g-cas-test.519611/

Using Gofer's procedure. CAS and CPS harness and sensors passed.

Used a noid light, all 4 injector pigtails light up.

Any update on this? Did you ever send in the ecu? My car does the same thing but if I keep it from idling it doesn't drop the injector.
