Aight, i have a 1995 GT, i bought the car with a motor recently put in it, the eplained to me that the motor come out of a 1970's bronco, he stated that he had to rewire the fuel injectors to match the firing order of the cam (how many firing orders does ford have?) the cam is a flattappet can, when i am driving the car it starts missing when i am cruzing at 55 in 5th, when im starting off it sometimes misses, and sometimes dont, i just put new oxygen sensors in, i cannot figgure out why it is missing, maybey its the cam, or the firing order of the cam isnt working with the computer.. any ideas? Thanxs, Z
