Code 18??

I was sitting in a parking lot for about 15 minutes with the car in neutral and all of a sudden it just died out for no apparent reason. It just went off like I shut the key off, but I didn't. I immediately tried to start the car again and it took a little longer than usual, but it did turn over.

I decided to scan it in case any codes popped up (No SES were tripped). It spit out 2 codes:

CODE 18 - NOT USED
CODE 77 - FAN 1 FAULT

I have had the CODE 77 come up before and am not too worried about that, but WTF does CODE 18 mean???

Bad wiring to one of you fuel injectors. Check to see if something is loose or cut possibly even worn through. Just my .02.

Good Luck!
