I have a golf 5 2.0 tdi bkd, and this morning I replaced the grommets of the injectors because there were traces of oil in the filter of the diesel, and because sometimes in the morning struggled to start. the engine until this morning it was a bomb, pulled down by fear. replaced the pads, reassemble everything, and I immediately notice a minimum quieter. so far so good. I go out with the machine, give it time to warm up and then I try on the highway. with the high gears it seems to have a fire1.2, when enter a couple shakes. at high rpm everything is almost ok, enough mushy-but do not tremble, at least. then rismonto the cover of the tappet, before I had logged the injectors to the stop - 180° now I put them in the 225. nothing to do always the same. now I thought, since the bolts that hold in place the injectors, I didn't narrow much, in fact I would be afraid that they are slow/spanati, it could be that an injector air bleeds and the compression was going to end up in the circuit of the diesel? I don't know just what to do. would you help me?
