Dave84 Posted 2 hours ago Posted 2 hours ago 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.
