So, I'm having some sporadic idling problems. The issue tends to disappear after I go a few miles and is definitely worst when first starting up the car. My RPMs seem steady, then decrease and then (correctively?) increases to the steady point and then the process repeats. It hasn't stalled itself out yet.
From my research thus far, there are several possible solutions:
- run a half a tank of 87 mixed with 93
- find and tighten up the loose 02 sensor (if there is one)
- ICV clean or replace
- DISA replace
- VANOS rebuild
Don't really know where to start. Is there any way to know which of these is the culprit? Your input would be appreciated. This seems to be a fairly widespread issue with the e46, so hopefully someone has run into it before. Thanks for your help!
