check engine light comes on randomly
lately i've noticed when i'm on the highway my check engine light comes on for about 20-30 seconds maybe a minute at most and then it goes away. Every time it comes on nothing happens to the car, it drives completely perfect. What could be causing this??

You have to jump out at 60mph and check the engine like it is asking.
What about temp? Im not sure if high temp will trigger a CEL.

My old F150 did this a few times. Turned out to be a bad ground.

Re: check engine light comes on randomly
Did you get the second piece of the header made and put on? If not,that's it right there. Mine did it when I had the a crack just after where the second piece header bolts up to the cat.
TILL IT REDLINES HACHI!!!!!!!!

Re: check engine light comes on randomly
mine did that constantly found it was the alternator plug kept popping out and i ended up zipting it in place as temp fix but i plan and putting a small bead of silicone on the connector and pushing it back in so it stays there
