shaking violently. I only notice this in 2 ways when driving which are reduced low end torque and revs rise quicker after rpm reachers around 1200. I have adjusted the Valves under 6000 miles ago so I highly doubt that. I read another post about the exact same issue where they sent the pump to be rebuilt and after no response so I guess it was the pump. I have never opened the injection pump so should I try removing the delivery valve for cleaning etc and should I try swapping two of them to see if problem goes over to the next cylinder? |

Your troubleshooting step was a good one (replacing suspect injector with a known good one) but better would be to swap the suspect injector with one from another cylinder. See if the problem follows the injector. Then, depending on the results, start looking at the delivery valves or other.

Friend gave me one from a 1.6d and it fit. I have never had them off so it must have been the doing of the previous owner but for some reason it just got worse lately and I only noticed it then. |

Wow! Missing spring would cause erratic injection behavior for sure! How long was it like that? Was it intermittent?
Job well done.

Now the gear shifter stays almost completely still and I can't feel the engine running when inside the car I'm amazed by the torque I have now because I can easily take off in 2 gear without any throttle. I instantly noticed a massive improvement in city driving because now I don't have to down shift nearly as much. I was just driving home and I didn't even notice my rpms were at 1000 in 4th gear when turning and the car didn't start shaking at all. Before I would have instantly noticed the crazy vibrations when rpms fell below 1500 and be forced to down shift into 3. The advice definitely helped a good bit in finding the issue. It was definitely delivery valve related but not in the way I was expecting at all haha |
