Some days ago, the cylinder head was serviced and the valves adjusted, because my car had an oil leakage that damaged the air sensor. At the same time, almost all the sensors were cleaned. However, it now happens that, when starting to drive, the vehicle suddenly stalls. The fuel pump has been checked and it seems to be alright. But the failure is still there and I do not know what else to check. Could you please give me your opinion?

Hi, buddies. I have a Kia Sephia II 2000 and its problem is that, when reaching half of the temperature, it starts choking. I then accelerate and it does not respond. I stop it, start it again and it works properly but only a block and the same occurs. I have already changed coils, fuel pump, wires, filters and nothing was solved. The scanner does not indicate any failure. I do not know what else to do.

My car has a problem with the fuel pump. I do not know why but, every time I travel, the vehicle overheats. The failure starts with a power loss, the car then chokes and I have to stop, in order for it to cool down. After that, it works properly for weeks. It is a quite strange problem the one I have. When it fails, I have to change the fuel pump and it lasts for a while.
