Hello everyone!
I have been having some unstable RPM idle around 750-1100 when stationary on my little 316i. However it does not happen most of the time, it happened more often during the winter
Any clue?? :cry:

Clean your idle control valve , first port of call .

could be blue temp sensor . could be TPS. NOT ADJUSTED RIGHT

Vacuum leak somewhere.
