    my check engine light is bipolar. it comes on and will stay on for a while and then one day out of nowhere it will shut off for a while and then repeat the same process. Any ideas on wat it could be or should i jus get it turned it off permanently? and how would i turn it off?

    Ever changed any of your O2 sensor(s)? Go to an auto parts store and have them pull the codes. The check engine light may only come on when the sensor is operating outside its parameters.

    View the build. Too much to list.
    If it's exhaust related, your truck has to complete certain steps when reading the o2 sensors. You have to be driving for 3 miles at a constant speed above 40 mph. Then it scans. So if your o2 sensor is flaky, it will come on when it reads outside the tolerance, but will go off if it reads okay. Assuming it's a o2 sensor....

    you'll probably have trouble codes stored. not much point in guessing till you get the codes.
