I recently purchased an 03 mustang gt. I have a couple of issues with it that im trying to get resolved. The anti left light continues to flash and stays flashing fast then gets slower until it eventually quits flashing after about 5 minutes or so. I bought a diablo tuner for my car and when i tried to install it for some reason it cant tell when i turn the ignition on and i believe this anti theft thing has something to do with it then when i took it to ford they hooked it up to their computer and tried to reinstall the factory tune and it still wont work he said because of the anti theft light flashing and my traction control wont turn off either any help would be appreciated thanks chad
