Thank you so much. the only code it has was 21. and unless my light blink counting isn't up to speed that means that the coolant temp sensor is bad. is this a common problem and how hard is it to change? if no reply. thank you again for all of your help.

ok so i am a newby to subaru and i do own a chiltons manual but i still cant figure out how to pull the codes on this car. its a 92 legacy, seems to run fine but the check engine light is on. is there any way i can get it to flash a diagnostics code at me? i read something about trouble code wires? please help.
