2003 Astro Service Engine Light

I have a 2003 Chevy Astro. When ever I tow anything and accelerate, for example to get on the expressway, the service engine soon light starts flashing. If I easy up on the gas the light goes out. Sometime the light will stay on but when I use the vehicle with out towing anything it goes out. In these situations will any codes be stored ? Has anyone else had this problem and know what causes it ?

I don't know your particular car but on many a flashing check engine light is to tell you that the problem the computer is detecting will destroy the catalytic converter. Codes are saved for a limited number of starts so if you take it in the next day after the light they should still be able to retrieve the trouble code.
