So are his injectors pretty much just dumping fuel?

(If that's the case)

It sure seems like it. Well do that check with the plugs, and see what's up. Thanks for the info.

Yes and No.

If say 2 of 4 injectors are not working then the other two functional injectors will be dumping more than usual to make up for the lean condition caused by the lack of combustion, as dictated by the ECU. We've already determined that the ECU does not know its malfunctioning by a simple code check. So, it continues to operate as normal. Because the 02 sensor is reading the AFR from both rotors it won't realize that one rotor isn't getting any fuel at all. Thus the lean condition, I think.

Anyhow that's how it worked on my car.

If the injectors are not grounding then they aren't opening at all. This explains the lack of power and odd idle.

Chances are, if one or more of his injectors are not being grounded by the ECU, then the ECU is detecting a lean condition and dumping more fuel into the engine.

This is the only way I can explain the rich condition.

I can go much more in depth with this, if you need me too.
