my bluedriver log

[patcal]

Greetings all,

This is for my 98 S70 GLT with 138k miles. I have a log file I read from my car. I have had a long running problem with a occasional stumble at idle. Was trying to see if it did it while logging. It did not. What I did notice is my O2 sensor #2 fuel trim really jumped from 4.4 up to 35. I am going to attach the file. Maybe someone with more knowledge then me(not hard) could look at it. Thanks in advance.
