Dan n Friends Help me trouble shoot my DPR trouble shoot tool.

You need to put the meter in series with the leads meaning that the meter
connect the circuit.  If You don't then the car won't run if the circuit is
open.  It should be high around 20 mA on a COLD engine.  As it reaches
operating temps it will drop and should stabilize around 7 to 10 mA  Some
people run it a bit richer around 5mA.  The lower the number the richer.
When making adjustments do it in very small amounts.  A very little twist of
the allen screw will change quite a bit.  Start with less than a 1/8 of a
turn if you need to adjust it.  Make sure the car is fully warmed up too.
That pretty short and sweet explanation.  HTH
