Computer problem
2000 Ford Mustang V8 Two Wheel Drive Manual 128,00 miles
----------------------------------------------------------------
i have a diablo sports tuner for my mustang, i was trying somthing new with the spark advance, and now i think my timeing is way off. i've tried switching back to the factory tune, and it will try and turn over but nothing more. i was told if i advance my timeing more, it should fix the problem if not i'd have to a dealer flash my computer. any ideas?
