Dave84 Posted Tuesday at 06:58 PM Posted Tuesday at 06:58 PM 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
Dave84 Posted Thursday at 03:33 PM Author Posted Thursday at 03:33 PM 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.
Trevor Posted 1 hour ago Posted 1 hour ago Sorry that no one responded to your post. One of the reasons on the old Micra 4 cylinder engine for poor idle was carbon build up in the throttle body. When it is cleaned out and refitted, you would then have to perform a reset on it through a diagnostic scan tool which should sort it
