Hi Mike:  When the cannister purge starts dumping fuel vapors into the 
intake it will cause the Fuel trims to drop because of the fuel added.
You can see what the cannister purge duty cycle is and what it probably does 
is force the BL idle cell to stay where it is when the duty cycle exceeds 
19.5%.
