my check engine light and trac off light come on whenever i get my car up to 80mph or above. ive reset the ecu and goes off but whenever i get to that speed it comes back on. has anyone else had this problem? its a 93 gs300.
thanks

You can pull the actual CEL code to determine the reason for the light.
Here is one site with instructions.

There is a more descriptive site I've seen but cannot remember the url.

 

Same lights, different scenario. Upon startup in the morning, both CEL and Trac Off lights illuminate, and then after about 5 minutes they go out and remain out. Is this also telling me to pull the CEL code? Or possibly something else amiss?
