Duration I thought was governed by a number of factors, primarily the pressure and temp sensors. That said, if that bank's trigger point is out of whack and were gummy and lingered (how this circumstance would arise, not sure), the ramifcations may or may not be interesting. Another thought- what if the trigger points were ok, but one side was making an intermittent contact? This wouldn't even have to be the points, but rather the circuit from the connector to the ECU. Wouldn't this result in extra firing of the injectors on that bank (changing frequency rather than duration). The only reason I'm thinking trigger points is because it's one thing thats common to injector pairs and it's a mechanical part thats subject to wear and stress. Not that anyone has something like this, but it would be interesting to hook up an oscilliscope to the trigger point pairs while running to see what the waveform looks for one side versus the other in this case. Is there another way this could be tested? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
