How good I have the next problem I have a Ford Topaz 4 cylinders Full Injection What happens to it is that it has as a relay detonations spends a lot of gas and well it has little power especially on the rise to the car, I already changed valve IAC, the acceleration body and oxygen sensor. The strangest thing is that only when it is hot and good in cold runs very powerful they will know or can help me with this. Since it is giving me more less 4 to 5 km per liter and well it adjusted motor a year ago and I miss me. For your help thanks
