Im still a newb when it comes to this topic. i have a 90 ex and i have always wondered how to read the codes. Im guessing it a series of flashes which corresponds to a code, right or wrong??

 

yea , on ur passenger side in the floor board there is a lil plug (u can put a paper clip in it ) turn ur car on not cranked and ur engein light will blink a certin number of times. Ur best best would be to go buy the haynes repair manuel at ur local auto zone or etc....
