Lean Mixture, Techron did it?

["Alexander van Gerbig" <Audi_80@email.msn.com>]

    As according to Bentley my current readings for the DPR are in the range
of 0-5mA when the engine is below normal operating temps.  BUT once the
engine begins to warm up to real operating temps the fluctuation goes to a
higher scale, 3.5-6.0mA.  I know that my fuel system, CISE-Motronic, is
adaptive to a degree.  An older engine with minor air leaks will run around
7mA during regular operation.  I haven't found any cracked hoses, no air
leaks to my knowledge.
    Now the real question, lately I come to a stop and the idle always dips
dangerously low then sputter back to life.  Assuming that mixture is lean,
could this be caused by running a can of Techron?  Maybe the Techron cleaned
valves up and now more air is moving through engine?  Clicking in rear of
cylinderhead is almost gone after Techron too.  Anyone, suggestions?  Idle
became rougher after Techron by the way.

Thanks again!
