Check engine light problem

I used a set of sparkplug non foulers to trick my 02 sensors, cost about $5.00.

I think I remember it all. Go to an auto parts store and ask them to show you a new o2 sensor for your truck, take it over to the spark plug non foulers, find one that seems like it would thread into. These come in a 2 pack. You will screw one non fouler into the other one. Then take a drill bit or a carbide burr tool and ream out the one you just screwed into the other. It needs to be big enough that your 02 sensor can screw into it. Once it is big enough, screw the non foulers into the o2 sensor hole on the exhaust system, then screw the o2 sensor into the non fouler. It lets the 02 sensor feel the heat, but won't foul out. I have had mine on for over two years and it has not come back on. I will see if I can find the link for pictures.
