So my check engine light comes on for about 10 to 30 secs sometimes longer sometimes less. Then just goes off. It isn't spitting any codes. I've tried several times. The only time the light comes on is goin down the road. What do you guys think?

Hate to say it but anyone who works on cars knows sometimes you have to wait for the problem to get worse to find out what it is. Meanwhile I would check electrical connections and grounds including the ecu connector. Electrical causes a lot of intermittent problems.

My truck does that after it warms up going down the road I can let it warm up idling no light go down the road light.
I assume its just because I don't have a cat.
