the next time this happens, im going to check the codes until then i was wondering if anyone had this problem.

When i get to about 80 -90 mph ( which is'nt that often) ..my new teg.. the check engine light comes on.

I know "check the ecu codes" was just looking for other input as well. will post codes after i get the light on again.
Thanks in advance

 

does it just come on and turn off???

 

it turns off after i turn the car off and back on.

 

I seen that on a neighbors teg. He gave me a ride and went about 90..his CEL came on. I told him and he said it does. Then we got to where I needed to go, came back never hit over 80 and no CEL....who knows

 

your car is telling you to drive the speed limit
