however there is one mystery, once in a while the reading while consistent 
with the correct range will be very high or very low,   but engine runs 
the same.

instead of 12-14
it will run 10-12
or 14-16

does this til I turn of engine and then when starting (sometimes within 
minutes) it will behave. I have checked all the connections??
