trying to compensate whatever is wrong.
It's not unheard of that fuelinjectors goes bad, but sort of rare on 9000.
Did you say that you had a voltmeter hooked up to O2 sensor while driving, and if so, what is it saying. O2 sensor is kind of the main part that tells the ECU to start compensating. It doesn't have to be the bad part but it feels all the disturbances (in the force) like injectors,AMM,coolantsensor,fuelpressure.
Most of the time it should osscilate between 0.1 V to 0.9V during coasting and idle.
When accelerating it should stay at 0.9V or close to it and when let go of throttle it should rest at 0.1V
My 2 cents.
