So I bought a 2008 Mustang GT 5 speed at the start of this year. I’ve previously had a 2006 and 2005 GT. This one ran right but the speedo hasn’t worked up until about a month ago. It started going into Failsafe engine mode with 8 codes coming up. I have replaced everything from cam position sensors to spark plugs and everything else. None of the codes have gone away even though I have replaced those specific parts. I’m starting to think it’s the computer itself. Any info would be wonderful, thanks. Jacob

I’ll have to look at the codes in the morning. I’m just taking it on to ford tomorrow anyway. I hate dealing with a shop but this is ridiculous. The engine light is on with 8 different codes. Both camshalf position sensors and 2 o2 sensors make up half of them. I can’t remember the rest of them though. And I replaced cam sensors and o2 sensors yesterday and it didn’t fix anything. ABS light isn’t on. It’s just the engine light and I drive it 50 feet and it’s in failsafe mode. It’s the weirdest thing. No one who has looked at it so far has a clue of what else it could be. I’m thinking the computer or a short in some wiring for the computer.
