Has anyone had any experience w/ the engine light turning on for about 10 min. and then turning off. What types of issues have arised? Currently testing car. Runs great, 1 owner, no major crashes just minor fender bender.

What year, make, and model do you have? I have no answers but I am about to post the following....

I have a 94' 626 ES-V6. At high-way speeds my check engine light comes on and then goes off after a few minutes or a minute or so after I get off the highway. I have OBD-1 and I have tested my vehicle, but it always says everything is fine (ie. no trouble codes). Does anyone know if OBD-1 codes are stored and should be retrievable after the problem-light goes out? I have never been able to turn my car off while the check-engine light remained on and test the OBD-1. I would have to pull off the highway, stop, and turn off the car very, very quickly. Is this the only way I can retrieve the trouble code from the OBD-1?
