Think I ave found what the problem is the air mixture sensor the one on the fuel injection system. If I disconnect it the vehicle runs without a problem can even reach 140km/h but reconnect it back the problem resurfaces again. Problem now is the vehicle now chews gas like no mans business guess it will improve when I get the thing replaced.
