I have had an intermittant CE light on my '94, seems like when it is raining (or after I washed the car). It fluctuates on and off. I know there is a brick sized module in front of the radiator, I don't know what it is, but it does get wet. I scanned the computer and got two memory codes:
#172 - Lack of heated oxygen sensor switches indicate lean bank 1
#173 - Lack of heated oxygen sensor switches indicate rich bank 1
Any ideas what the codes mean and if it could be related to the "brick" and it getting wet (maybe bad connection or something?)
Thanks in advance.
