In damp/rainy weather my car had difficulty starting and ended up with the check engine light on/cruise automatically disabled. Subaru rec replacing the A/F & O2 sensor relay. But dealer later said they didn't replace the O2 relay because the code for it wasn't tripped.
5 months later after car was sitting in parking lot for several days and it was raining, the car had difficulty starting and the symptoms are the same as before. I haven't brought it in to check if the diag code is the same one.My question... I don't want them just to replace the A/F sensor without finding the cause of the problem. Any ideas out there about a sensor problem associated with damp/rainy weather?
