Sounds like plugs as Pud says, but if you still want the resistances for CF2 engine they are:-
Primary: 0.3 Ω +/- 12%
Secondary: 7 kΩ +/- 12%
Checked on a new genuine spare I have the loft and the primary is measured through the two small connectors on the top of the coil. I measured 15kΩ through the two HT poles. However for the CF3 engine I believe values are different. I'll look. Found it, 13 500 ohms for the secondary.

How old are the spark plugs, and are they the proper NGK laser platinums?
From one HT pole to the other HT pole. They are the two large brass connectors.
Ok, taking cylinder 1 as nearest the cam belt, I've removed, cleaned and individually tested each one. Spark plug 1 recess was oily, recess 2 less so, cleaned out both. Battery voltage with engine off was 12.32 volts, with engine running 13.90 volts and with engine running, positive terminal to earth was 13.95 volts. Harness side, pin 1 voltage on each plug was dead on 12.32 volts with the ignition on. Those are checks from the linked to PDF.
Resistances are as follows...
Coil pack 1, primary 1 ohm, secondary 16.38 kilohms
Coil pack 2, primary 1 ohm, secondary 16.18 kilohms
Coil pack 3, primary 1.1 ohms, secondary 15.78 kilohms
Coil pack 4, primary 0.9/1.0 ohms, (wouldn't settle), secondary 15.76 kilohms
One of the coil packs had a crack in part of the housing and one had a kind of green powder coating the connectors, pics to follow. These are the coil packs from Autolusso. I'll check and test the ones I removed tomorrow and see if I can more accurately match up a set of 4. But at the moment, for the set on the car, primaries seem low, secondaries seem high...
