Can someone help....
What does code 98 mean? "Did not pass KOEO yet (Get 11 in KOEO first)"

I have a 91 Ford Mustang V8.

Thanks in advance,
Jason

Code 98 - basic computer internal tests not passed before it started processing the request to dump codes. Do a Key On Engine Off test before starting the engine. Wait until you see the 11 flash before pressing any buttons if you have a hand operated scanner. The computer is operating in Limp mode, so fix any codes it dumps prior to doing anything else.
