as most of you have probably heard....in buffalo, ny here, we got slammed with lots of snow.....while i have beening driving on these snowy wet roads the last 2 days.... my CEL has been coming on for a minute, then goes off for a minute or so, and then comes back on and off.

i am guessing maybe the o2 sensor got touched by something.

what would make this light go on starting on a snowy day?

thanks

 

No use guessing - you need to know the trouble code. Here are instructions for getting the code without using a puller. This works on Rangers through 1994:
