Pode ser o avanço do avanço (progresso ou atraso no momento da injeção), se o tiver cancelado e começa bem, eles podem ter a bomba de supervisão (rascunho inicial) e, em seguida, alguns cancelam a eletrovalação do progresso para evitar o avanço excessivo. The reason for this in this engine is due to a typical and well -known breakdown of the crankshaft and pineapple, the pump and distribution are behind, and some correct it by doing this "fudge", because the repair when this chamba is presented, is screwed ... It may not be your case, but you can take an eye on the pinon and your key and leave doubts (I have seen cases of people who have looked to change bombs in these engines and then have seen the problem of o pinhão ...). Espero que não seja o seu caso. Sorte!!
