At the end of my rope with this stinkin cis

[Brendan Walsh]

I'm running cis-e in an 87 cgt, meter was hooked up in series with the dpr 
The meter is always reading 1.01mA when the car is running or not, warm or 
cold. if i disconnect the meter the car get's erratic, reconnect the plug 
and it smooths out. if i switch the meter to the uA(micro amp) range i can 
see slight variations+/- 2 uA. It should be in the 10 mA range correct? 
SHould i be hooking up the meter in parralell? Could it be screwing up the 
circuit?
