Can someone please help?

I just bought my e90 m3 and was driving and when I came to a stop the Rpm's dropped and then went back up and dropped again as if it were about to shut off has this happen to anyone or am I just worrying for no reason ? It's 2011 with 61k thanks in advance for any info

Fuel tank breather valve. Had you just gotten gas?

Even though I've never had this problem I appreciate your time and VERY detailed write up on how to DIY to fix it! Kudos...

Yes def big thank you I'm actually ordering thebparts Monday 😁😁

no problem. typically the issue happens after getting gas when it is the breather valve. that's not to say your issue isn't the breather valve and at $80 it's worth a shot but keep in mind it may be something else. I would start where I said though.

Ok def a good start. The car hasn't done it again but I'm going to change it anyways
