check the code that is being thrown. you do this by jumping the service connector (its a two wire connector just hanging down by the ecu, just bend a wire and stick it across the two holes in the plug)
then put your key in the ignition and turn it to acc/on, your cel light will blink at you, count the blinks
long blinks for 10's digit, short for 1's
long...long...short.short.short = 23
get it?
