Well after the influx of msg on here 😒 I bit the bullet and bought 3 new coil packs. Turns out the readings I gave above are correct and I didn’t need the 150 quids worth of coil packs.

Kind of resolved this now a bit. It still has a slightly rough idle in my opinion but it is a 3 cylinder so could just be the nature of the car?? any way I metered out the coil packs all seem to be the same and as I don’t know what they are supposed to be I’m going with they are ok? I also unplugged them one by one and the engine started to misfire as expected. I removed the throttle Body and gave it a good clean. It wasn’t too bad but there was a little bit of oil in there. I also unplugged the fuel solenoid purge valve and let it run for a second or so and plugged it back in. I also found that both battery terminals were very loose! So they got tightened up as well. Since doing this it seems to idle better. The only time the revs seem to hunt is when the ac is on now and the highest it goes is up to about a 1000 when the clutch kicks in which I’d kind of expect as there is extra load on the engine.

Hi does any one know what the resistance values across the coil pack should be? my 2017 micra is running a bit rough and hunts on idle but I can’t see or hear any air leaks. iv serviced the car including new iridium plugs and just put a full tank of premium fuel with red ex fuel cleaner init. I’m kinda running out of options on what this could be. Next step is to clean the throttle body but I’m thinking possible coil pack issue as well. im getting 79.4kohm between pins 1&3 and 0.47Kohm between pins 1&2 and 79.45kohm between pins 2&3 and that’s on all 3 coil packs as well ( slight differences between them) there is no EML light on the dash either and my scanners are not picking any fault codes up

Hi Iv just picked up a 2017 micra with the 0.9ltr engine in from Copart. It’s got a slightly rough idle, Iv just replaced the plugs and oil and filters on the car as I don’t know the history. It’s done 54k miles the evap system seem to be working ok. I don’t have a vacume pump to check properly but it’s not getting blow by out the dipstick or the filler cap. im a bit to remove the throttle body and clean it but after this I’m kinda stumped. Unfortunately my code reader is showing nothing on the system and there is no lights on the dash. Short of replacing all the coil packs I’m stuck. Any ideas?? on start up it also has a high idle as well seems to sit around 1500 and then drops off to around 800. I’d expect this on a cold morning for the cold start but it’s not been cold.
