[QUOTE="jarance, post: 382216, member: 21"] My E46 when first start will have a RPM at about 900 rpm when cold start. Once it warm up, the RPM will dropped to 850 rpm. There is a thread about DIY (cleaning) the MAF. In most cases, the RPM will be stabilize if the MAF is dirty due to clogged filter and dust sticking on the hot wire of the MAF. If the ICV is a problem, then you will have idling speed regardless whether the engine is cold or hot. Somebody is offering to clean the MAF for about RM50 which include material and come to your house. [/QUOTE]
