I have not done anything about mine yet, but I have to do something soon, as my truck is due for NYS inspection, and I believe they might not pass it with the check engine light on. I suppose I should go back to the dealer where I purchased the truck used, but they are over an hour away, and not the most friendly group to deal with to date....but I gotta do something...
