84 300 vibration at 1500 or so

It all started after I had run the car up a mountain with curvy roads. I pushed the car a bit (not to hard)after that it started idling rough. Thought it might be injectors leaking. I changed and set injectors. It ran better. Now it has a rough idle and a strong vibration at around 1500 rpm feels like it vibrates the whole car. Also it seems to be have more valve noise when idling, maybe nailing? adjusted valves 2 times.
