I haven't run my supra all winter and I started it up the other day and drove it and it seemed fine. So today I took it for a short drive and on the way home I felt it missing a little. As I pulled into the driveway I and I was positions the car to pull into the garage it stalled. I was able to start it again even though it seemed like it wanted to stall again and I pulled it into the garage. The check engine light was now on and it threw a code 31. I guess I need to check out the AFM??? Anyone have any input? Also the garage I just started parking my car in since I purchased a new house is pretty humid. Not sure if that matters??

Also...I think I remember this happening a long while back and the problem seemed to just go away after playing with the AFM connection.

I would say just mess around with it also clean it with electrical parts cleaner, I had the same issue with mine after 6 months of letting it sit. Not sure if it was code 31 though. Also im pretty sure humidity isnt a problem, maybe larger amounts of water but humidity should effect it to my knowledge or you could just replace the connector.
