Default Ms3pro pnp EGO going crazy

I alredy posted this in my build thread but i think this is the correct place to post.

Something strange started to happen. The car was running very lean. I connected my laptop and the EGO correction was going crazy 85%. Note that the car was running great (i did not make any changes to it) until yesterday night. Today it started right up and everything was normal and EGO was working great. While i was driving, out of the blue it started doing again the same thing. EGO was stuck on 85% I turned it off and the car started working good again. Has anyone experienced anything similar? Is there a possibility that my ms3 is fucked up?

Are you sure your wideband is working properly? Or the connection to the ECU is secure?

How did you ascertain that the car was running lean? The ECU definitely thought it was running rich accoroto the EGO response
