Hi,
I assume neither.
Please tell us your exact measurement circuit.
Tell us the expected circuit of the ignition coil.
And the manufacturer and tyoe of your capacitance meter.
We can just guess:
You are measuring primary to primary.
If now the ignition coil is a standard coil without other internal parts (like a capacitor) then the expectable parallel capacitanceshould be in the high pF range up to low nF range. (mind that there could be a series capacitance, too)
70uF and more is definitely too high....
