How do I manually draw codes on my 99 infiniti I30
You can try the instruction from here: http://infinitihelp.com/diy/common/infiniti_engine_codes_read_2.php
Sometimes the reading the codes without the scanner is not very accurate, most auto parts and some shop will check the codes freee for you.
I dont think this car had it. Most auto parts now offer free code reading, call and ask around.
