Ran rich
 

I started the car, for the first time in about a month, a few days ago. It started normally. After a quick warmup I started to drive and it started to have afrs in the 10s. I shut it off and checked my vacuum lines and they looked fine. I restarted and it ran normal. I drove it 300 miles that day with no issues. Was this just an anomaly or signs of a future Ms failure?
