hey guys a few minutes ago i pulled into my driveway and all of a sudden my cel comes on. im like wtf so i turn it off and turn it back on and its not there anymore. what was going on with that? btw i drive a 1990 rs

 

plug the connector to see if your flashing any codes in memory.

 

i said it was 1990 rs because that is obd0 and on obd0 you dont plug any connector you just look at the led intside the ecu...thanks anyways

 

pull the carpet back, it still might be flashing a code... if not, try to trip the code then try to read it out. sometimes you get a code like coolant temp sensor cause you have a bad radiator cap (doesn't hold pressure) and it will only trip it sometimes, not all the time.
