after cleaning the throttle body a month ago the problem seemed to have gone away.
now the same rpm fluctuations seem to be back, especially noticeable when coming to a stop. fluctuating rpm between 400 and 1000 but it does not stall. seems to recover very quickly again.
the car still seems to be a little bit harder to start too. It does crank well so starter motor and battery is ruled out, but especially when the car is warm after a short drive, it might take 2-3 seconds of cranking before it fires up.
according to the service history a ECM update and new sparkplugs have been done 8 months ago. So the software should be up to date.
sensor problems? The car does not have any fault codes though.
