It can be the advancement of advance (progress or delay the injection moment), if it has it canceled and starts well, they may have the oversight pump (initial draft), then some cancel the progress electrovalve to avoid excessive advance. 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 pinion and your key and leave doubts (I have seen cases of people who have been changing to change bombs in these engines and then have seen the problem of the pinion ...). I hope it is not your case. Luck!!
