You could test coil resistance :
Resistance measurements of the primary and secondary sides of the ignition coils can be performed using a suitable multimeter. Default values are:
• Nominal primary coil resistance (up to 99MY) = 0.8 ohms
• Nominal primary coil resistance (from 99MY) = 0.5 ohms ± 0.05 ohms at 20°C (68°F)
• Nominal secondary coil resistance = 13.3 k-ohms ± 1.3 k-ohms at 20°C (68°F)

Grab a spare spark plug pull the caps off one at a time connect to spare plug crank engine see if you get a spark don't forget to earth the plug, simples.
The tester costs more than replacement packs I bet.

I had a lot of engine misfires over a period of time and the indie replaced a single HT lead each time saying that it had fixed the problem. Eventually we agreed that "death by a thousand cuts" was not my idea of fun and I had them change both coil-packs and all 8 leads.
Not a "skinflint" solution but the packs and leads were cheaper than 8 x visits and tech time and inconvenience to me being without the vehicle.

Hard to say which is nastiet. O2 sensors have probably welded themselves in place by now and the dis-pack is buried behind so much **** you think it would last forever.

If you are changing O2 sensors that have been in a while you'll most likely need oxy torch for heat and a big pair of stillsons get the range up high put axle stands under it get the threads nice and hot and work back and forwards. They will wind out with time you can get an O2 sensor thread chaser that's how I got mine out.
On the Coil packs if you have the thor/bosch moronic system the a faulty coil pack will show as a misfire on two cylinders being the corresponding plug lead as they are redundant sparking.
I can answer about gems. However check the HT leads as the plug into the Coul pack can pick up corrosion and break down.

Pretty sure the GEMS is the same with a redundant spark.

Flat numbers like that aren't very informative. Use your Nano to record some live data, then you'll be able to see whether your lambda sensors are flipping as they should.
Screenshot only for illustration. Your results will differ!

Can't remember Pete. Looking at the durations probably just engine running.
Use the official Nano CSV viewer on your PC with the Nano plugged into it to see the charting as above. Of course you'll need the SD card in your Nano to record the data in the first place.
Ok cheers I did try it before but had to get my son to convert the data on windows word or one of them programs and it took an age I've I get on that csv veiwer it should just convert the files then I'm just sorting another problem 1st ordered a new crank sensor from island 4x4 mistake just looked at nanocom propley and fink its camshaft sensor I need oh well more spares

Rare for a cam sensor on a GEMS to actually fail. Common for the connector to the cam sensor to fill up with gunk thus "failing" the cam sensor.
Check it's clean and that all wires are intact before splashing out megabucks.
CSV Viewer is available from the Support & Downloads section of the Nano site, or if not there, it'll be in your private downloads section.
